List of DMP-Sponsored or Co-Sponsored Focus Topics and Sorting Categories for the APS March Meeting 2016

7.1.1: Dielectric and Ferroic Oxides (DMP/DCOMP/DCMP)
Organizers:

Manfred Fiebig (ETH Zurich)

Dillon Fong (Argonne National Lab)

Complex oxides exhibit a rich variety of order parameters, such as polarization, magnetization, strain, charge and orbital degrees of freedom. The vast range of functional properties that emerge from their mutual coupling (e.g., ferroelectricity, magnetoelectricity, multiferroicity, metal-insulator transitions, defect-related properties) are the main topics of interest for this symposium. Examples of current grand challenges include:

Novel mechanisms to break inversion symmetry in heterostructures and layered oxides.
Viable routes to achieve a strong coupling between polarization and ferromagnetism at room temperature.
Band-filling and bandwidth control in complex oxides (a prerequisite to harnessing charge/orbital order, magnetic transitions and metal insulator transitions).
Electric- or magnetic-field control of these phenomena - a very exciting prospect for both fundamental science and technology.
Structure and properties of magnetoelectric domains and domain walls of these materials.
Emerging avenues to controlling polarization, magnetism and electronic properties via strain and/or strain gradients and/or defects.

Breakthroughs and progress in the theory, synthesis, characterization, and device implementations in these and other related topics are solicited for this Focus Topic.

7.1.2: Topological Materials: Synthesis and Characterization (DMP/DCMP)
Organizers:

Peter Armitage (Johns Hopkins U)

Feng Liu (U. Utah)

Sean Oh (Rutgers)

There has been explosive growth in the study of topological materials in which the combined effects of the spin-orbit coupling and fundamental symmetries yield a bulk energy gap with novel gapless surface states robust against scattering. Moreover, the field has expanded in scope to include topological superconductors, Dirac and Weyl semimetals, Kondo insulators and complex heterostructures capable of harboring exotic topologically nontrivial states of quantum matter. The observation of theoretical predictions depends greatly on sample quality and there remain significant challenges in identifying and synthesizing the underlying materials having properties amenable to the study of the surface and interface states of interest. This topic will focus on fundamental advances in the synthesis, characterization and modeling of candidate topological materials in various forms including bulk single crystals, exfoliated and epitaxial thin films, epitaxially modulated heterostructures, nanowires and nanoribbons, and theoretical studies that illuminate the synthesis effort and identify new candidate materials. Of equal interest is the characterization of these samples using structural, transport, magnetic, optical and other spectroscopic techniques, and related theoretical efforts aimed at modeling various properties and the underlying spin-textures, spin-splittings and substrate effects, with particular focus on identifying samples whose properties are dominated by the surface and interface states.

7.1.4: Strongly spin-orbit coupled oxides/emergent entwinement (DMP)
Organizers:

James Analytis (UC Berkeley)

Natalia Perkins (U. Minnesota)

Xingjiang Zhou (Institute of Physics, Beijing)

Strong spin-orbit coupling (SOC) has played a central role in some of the most exciting discoveries in materials over the last few years. SOC is important for driving topologically non-trivial band structures, leading to spin-momentum locking in Rashba materials, protected surface states in topological insulators, and ultra-relativistic Dirac and Weyl quasi-particles in exotic metals. Moreover, SOC can strongly affect many-body phenomena, leading to complex broken symmetries in multi-ferroic systems or strong frustration in quantum magnets. Indeed, SOC materials are currently at the forefront of research into spin liquids, whose excitations are thought to be highly exotic, even having fractional quantum numbers. Research has largely focused on binary/ternary high-Z materials with weak correlations and mixed orbital character and transition metal oxides with strong correlations and complex competing interactions. The physics of SOC materials thus connects to some of the deepest problems in condensed matter, from topology to correlated electron phenomena. The scope of this Focus Topic will encompass 4d- and 5d-transition-metal compounds, rare earth compounds, and heavy chalcogenide compounds that exhibit a wide variety of SOC-related physical phenomena including metal-insulator transitions, Mott insulator formation, strong Rashba splittings, strong magnetic anisotropies and superconductivity.

7.1.5: Organometal Halide Perovskites; Photovoltaics and beyond [also 12.1.11] (DMP)
Organizers:

Mercouri G. Kanatzidis (Northwestern)

Z. Valy Vardeny (University of Utah)

The field of thin-film photovoltaics (PV) has been recently enriched by the introduction of the remarkable class of hybrid organic-inorganic semiconductors, such as lead halide perovskites (for example CH3NH3PbI3), as absorber materials which allow low-cost synthesis and fabrication of PV solar cells with efficiencies exceeding 20%. The physicochemical attributes of these compounds have lead to their rapid emergence as serious candidates for cheap PV solar cells, and has raised immense interest in their fundamental physical properties. Understanding the exact impact of the crystal structure and composition on the optoelectronic properties of the hybrid perovskites is the focus of intense research at the present time. In crystalline materials, exciton diffusion length of the order of hundreds of micrometers and carrier mobilities exceeding 1000 cm2/volt*sec have been reported. Also their relatively strong photoluminescence emission has lead to several laser applications, and fabrication of efficient light emitting diodes. These compounds show several structural phase transitions at various temperatures that may complicate the interpretation of the physical properties and/or modify their optoelectronic properties driven by substantial changes in the exciton binding energy. In addition the strong spin-orbit coupling of these compounds have lead to interesting magnetic properties, and the dipole moment associated with the organic molecule in the unit cell may lead to ferroelectricity.

8.1.2: Dopants and Defects in Semiconductors (DMP/FIAP)
Organizers:

Christoph Boehme (U. Utah)

Pat Lenahan (Penn State U)

Impurities and native defects profoundly affect the electronic and optical properties of semiconductor materials. Incorporation of impurities is nearly always a necessary step for tuning the electrical properties in semiconductors. In some cases, as in dilute III-V alloys, impurities even modify the band gap. Defects control carrier concentration, mobility, lifetime, and recombination; they are also responsible for the mass-transport processes involved in migration, diffusion, and precipitation of impurities and host atoms. The control of impurities and defects is the critical factor that enables a semiconductor to be engineered for use in electronic and optoelectronic devices as has been widely recognized in the remarkable development of Si-based electronics, the current success of GaN-based blue LED and lasers, and the emergence of ZnO for nanoelectronics sensors, and transparent conducting displays. The fundamental understanding, characterization and control of defects and impurities are essential for the development of new devices, such as those based on novel wide-band gap semiconductors, spintronic materials, and low dimensional structures.

The physics of dopants and defects in semiconductors, from the bulk to the nanoscale, including surfaces and interfaces, is the subject of this focus topic. Abstracts on experimental and theoretical investigations are solicited in areas of interest that include: the electronic, structural, optical, and magnetic properties of impurities and defects in elemental and compound semiconductors, SiO2 and alternative dielectrics, wide band-gap materials such as diamond including NV centers, SiC, group-III nitrides, two-dimensional materials including phosphorus and BN, oxide semiconductors, and the emerging organic-inorganic hybrid perovskite (e.g., MAPbI3) solar cell materials are of interest. Likewise welcomed are abstracts on specific materials challenges involving defects, e.g., in processing, characterization, property determination, including imaging and various new nanoscale probes.

9.1.1: Fe-based Superconductors (DMP/DCOMP)
Organizers:

Ian Fisher (Stanford U.)

Peter Hirschfeld (University of Florida)

Jenny Hoffman (Harvard U./U. British Columbia)

Substantial experimental and theoretical progress has been made toward understanding the unusual normal and superconducting state properties of iron based superconductors (IBS). Yet, many challenges and controversies exist, often driven by recent discoveries of new or improved materials whose properties differ radically from the original set. Among the current challenges are the origin of the dramatically enhanced Tc in single-layer FeSe, and the reasons for nematicity without long range magnetic order in bulk FeSe. This Focus Topic will cover the latest experimental and theoretical issues pertaining to both normal and superconducting properties of IBS and their parent compounds, both pnictide and chalcogenide based. By better understanding the relationship between these two families, how the different crystalline, magnetic and electronic structures in IBS relate to the high critical temperatures, and how the these systems compare to cuprates and other novel superconducting materials, the goal is to enhance the potential for discovering new superconducting systems with higher Tc's.

12.1.1: 2D materials: synthesis, defects, structure and properties (DMP)
Organizers:

Chongwu Zhou (USC)

The interest in two dimensional (2D) materials is rapidly spreading across all scientific and engineering disciplines due to their exceptional chemical, mechanical, optical and electrical properties, which not only provide a platform to investigate fundamental physical phenomena but also promise solutions to the most relevant technological challenges. 2D materials find their immediate application in field effect transistors, gas sensors, bio-detectors, mechanical resonators, optical modulators and energy harvesting devices with superior performances that have already been demonstrated in prototype devices. However, the true impact will only be made if the initial breakthroughs are transformed into commercial technologies. A major challenge towards the commercialization of 2D materials is the large area, scalable and controllable growth of highly crystalline layers in a cost effective way. So far the best quality samples of 2D materials have been obtained through micromechanical exfoliation of naturally occurring single crystals. Chemical vapor deposition (CVD) is the most widely used bottom-up technique to grow large area 2D-materials. Several top-down approaches have also been adopted based on bulk liquid phase chemical and electrochemical exfoliation. The 2D focus topic will cover:

Experimental, theoretical, and computational studies illuminating various aspects of the growth process including, e. g., layer number and stacking geometry control, the formation of topological and structural defects, grain size and grain boundary control, and the effect of substrate chemistry, crystallography and strain
Methods of doping
Templated or bottom-up growth or top-down synthesis of nanostructures and integration with other materials

With the rapid progress in the research on 2D materials, including graphene and other layered material systems, a wide variety of properties and functionalities have emerged that have broad scientific and technological significance. The rational design of devices consisting of 2D materials calls for improved understanding of their intrinsic and extrinsic properties that are critical to the device functionality, as well as their integration with other device components. The development of these 2D materials based devices also requires solutions to problems associated with material functionalization, structural fabrication, and device characterization. This Focus Topic will cover experimental and theoretical/computational work related to devices based on the growing array of 2D materials that exhibit a wide variety of behaviors – such as metallic, semiconducting, insulating, magnetic, superconducting, and various strongly correlated electronic phenomena.

12.1.6: Van der Waals Bonding in Advanced Materials (DMP) (DCMP)
Organizers:

Martin Head-Gordon (University of California, Berkeley)

John Singleton (Los Alamos National Laboratory)

Van der Waals interactions are ubiquitous in nature and play an important role in the structure, stability, and function of molecules and materials studied across all of the major disciplines of science, ranging from structural biology to supramolecular chemistry and condensed matter physics. While van der Waals interactions are considerably weaker than covalent bonds they have structure-directing ability and often control the physical properties of a material. These non-bonded interactions are inherently quantum mechanical in nature and result from dynamical correlation among collections of electrons, and remain a substantial challenge to experimentalists and theorists. Hence, the aim of this Focus Topic is to directly address this challenge by highlighting the current state-of-the-art in materials design and synthesis, as well as experimental and theoretical approaches to better understand van der Waals interactions. In doing so, we hope to lay the groundwork for future collaborative research - an approach that is necessary for describing these fundamental interactions in materials of increasing complexity.

Advances in algorithms, computational power, and the ability to predictively model physical phenomena are spurring the computational discovery and design of novel materials, allowing for virtual materials synthesis and characterization before their realization in the laboratory. This focus topic will cover studies at the frontier of computational materials discovery and design, ranging from quantum-level prediction to macro-scale property optimization. Topics of interest include, but are not limited to: Computational materials design and discovery, high-throughput computation and automatized data analysis, computational materials databases, materials informatics, data mining, machine learning, global structure and property optimizations, algorithms for searching the structure/composition space, first principles property prediction and methods for improved accuracy or efficiency, computational modeling of materials synthesis. Of particular interest are contributions that apply novel data/computation-intensive approaches to materials design, that feature a strong connection to experiment, and those that translate physical insights gained from computation into advanced materials by design. The application focus broadly covers electronic materials, ranging from low-power electronics (Mottronics), energy conversion and storage materials (thermoelectrics, batteries, fuel cells, photovoltaics), to novel materials for non-linear optics and data processing (spintronics).

13.1.1: Nanostructures and Metamaterials (DMP/DCMP)

Vivian Ferry (U. Minnesota)

Jeremy Munday (U. Maryland)

Michael Naughton (Boston College)

13.1.2: Many-body perturbation theory for electronic excitations in materials (DMP)
Organizers:

Volker Blum (Duke)

Claudia Draxl (Humboldt University of Berlin)

Thomas Koerzdoerfer (U. Potsdam)

Noa Marom (Tulane)

Many properties of functional materials, interfaces, and nano-structures derive from electronic excitations. For example, the ionization potential, the electron affinity, the fundamental gap, dielectric screening, charge transition levels of defects or dopants, and the energy level alignment at interfaces are associated with charged excitations. Conversely, the optical gap, absorption spectra, and exciton binding energies correspond to neutral excitations. These properties are critical parameters for the performance of devices, such as transistors, light emitting diodes, and solar cells.

A proper description of electronic excitations requires theoretical approaches that go beyond ground state density functional theory (DFT). Methods originating from Green’s function based many-body perturbation theory are a natural choice. In this framework, the random phase approximation (RPA) accounts for dynamic and long-range correlation effects (e.g., van der Waals interactions) manifested in the dielectric function and in the energetics of weakly bonded systems. The GW approximation, where G is the one-particle Green’s function and W is the screened Coulomb interaction that derives from the dielectric function, provides an accurate description of charged excitations and the Bethe-Salpeter equation (BSE) of neutral excitations (including charge transfer excitations).

This focus topic is dedicated to recent advances in many-body perturbation theory methods for electronic excitations, their scalable implementations in electronic structure codes, and their applications to functional materials, interfaces, molecules, and nano-structures.

13.1.3: Electron, Ion, and Exciton Transport in Nanostructures (DMP/DCMP)
Organizers:

Pierre Darancet (Argonne National Laboratory)

Alec Talin (Sandia National Laboratories)

Understanding the transport of electrons, ions, and excitons in nanostructures is critical for realizing the potential of nanoscience and next generation device technologies. Of particular challenge, and opportunity, for understanding transport in nanostructures is the impact of interfaces, shapes, electronic confinement, interactions and quantum effects. This is particularly true of hybrid, complex nanomaterials of different compositions and phases that can have varying degrees of electronic and optical couplings and interactions. Depending on the composition and geometry, couplings (electromagnetic, Coulomb, ballistic, tunnel, etc) can be weak or strong. Structural components used in hybrid nanostructures can be made of semiconductors, metals, molecules, liquids, etc. Correspondingly, elementary excitations responsible for optical and transport responses of such nanostructures include excitons, plasmons, electrons and ions.

Contributions are solicited in areas that reflect recent advances in experimental characterization and theory of transport mechanisms in inorganic and hybrid nanoscale structures. Specific topics of interest include, but are not limited to:

Excitonic nanomaterials with light-harvesting and lighting properties utilizing both solid-state and molecular components

Complex oxide heterostructures display a range of impressive multi-functionality, encompassing superconductivity, colossal magnetoresistance, magnetism, multiferroicity, and strongly correlated Mott-Hubbard insulator-type behavior in addition to novel interface-stabilized ground states such as two-dimensional electron gases (2DEGs), 2D superconductivity, novel magnetism, and topological phases. The extreme sensitivity of these phenomena to composition and interface structure offers endless possibilities for fundamental studies of the interactions between the structural and electronic degrees of freedom that give rise to these fascinating phenomena, and thus providing many insights into materials physics in addition to the capability to design completely new devices. Local symmetry breaking, charge transfer, magnetic and electrostatic interactions, and coupling between structural modes are just some of the many mechanisms that can lead to the appearance of novel interfacial functionalities and can be employed for rational design of artificial materials with desirable structural, electronic and magnetic properties.

The aim of this focus session is to provide a forum for the discussion of recent experimental and theoretical results on complex-oxide heterostructures and their interfaces. The topics covered in this session will include advances in the growth and characterization of complex-oxide heterostructures, development of interface-related measurement techniques, theory and modeling of oxide heterostructures and interfaces, experimental investigation and tuning of interface-related properties in conducting, insulating and magnetic oxides, chemical and electrochemical effects in manifestation of physical functionalities, applications based on interface-related phenomena in complex-oxide heterostructures, and new phenomena appearing in complex oxides owing to heterostructuring.
