    Thin Films of Topological Magnets for Thermoelectric Applications

    May 28, 2024

    A thin film of a topological magnet displays a large thermoelectric effect that doesn’t require an applied magnetic field—a behavior that could lead to new energy-harvesting devices.

    Fermiology and transport properties of the candidate topological crystalline insulator SrAg4Sb2

    Inspired by the nonmagnetic topological materials database, the authors investigated the 3D fermiology and band topology of the Topological Crystalline Insulator (TCI) candidate SrAg4Sb2. The fermiology, revealed by angular-dependent quantum oscillations, shows excellent agreement with first-principles calculations. Symmetry and topology analysis result in two potential sets of topological invariants, suggesting the emergence of crystal-symmetry-protected gapless Dirac surface states either on the as-grown ab planes or on both the ab planes and as-grown mirror planes. Their findings provide evidence that SrAg4Sb2 is a promising TCI for exploring topological surface states protected by crystal symmetry.

    Fidelity and variability in the interlayer electronic structure of the kagome superconductor CsV3Sb5

    A reliable interlayer band structure of the kagome superconductor CsV3Sb5 is critical for understanding emergent phenomena like the charge density wave ordering and for classifying the topology. Here, the authors present a survey of computational techniques aimed at comparing the electronic interactions between kagome layers in CsV3Sb5. This study highlights the computational parameters and plotting methods that lead to differing band behaviors. Within conventional DFT, the parameters employed during structural relaxation are critical in determining the electronic structure between kagome layers. However, higher levels of computational theory contrast these results and point to the increased role of interlayer interactions.

    Ultrashallow heavily constrained quantum wells: The cradle for fully electrically controlled and microwave coupled quantum bits

    The study focuses on the systematic growth and characterization of material properties, as well as the low-temperature transport properties, of ultrashallow heavily strained quantum wells. A new characterization method, called Density of Stress Accumulation Points, has been introduced for assessing quantum well strain. An ultrashallow heavily constrained quantum well with a remarkable mobility of 3.382×105 cm2/Vs was successfully achieved. This achievement serves as the foundation for the development of fully electrically controlled and microwave cavity-coupled quantum dot materials.

    Disorder-driven localization and electron interactions in BixTeI thin films

    In this work, we investigate the effect of strong disorder on BixTeI thin films, revealing a metal-insulator transition that depends on composition and the growth temperature. Understanding how disorder can be used as a parameter to alter the electronic properties of a material goes beyond the conventional understanding of crystalline material conductivity. This study therefore highlights the role of strong localization in disordered materials in shaping emerging quantum properties.

    High-throughput hybrid-functional DFT calculations of bandgaps and formation energies and multifidelity learning with uncertainty quantification

    The authors computed bandgaps and formation energy values of more than 1100 crystalline materials‬ using Density Functional Theory (DFT) with HSE‬ and PBE approximations of the pseudopotentials. They analyzed accuracies of HSE and PBE approximations among different classes of materials. They also built a multi-fidelity machine learning model to predict the bandgap at HSE accuracy when a material’s PBE bandgap‬ is known. The new high-throughput DFT (HSE, PBE) data of more than 1100 materials and the predicted‬ HSE bandgap data of more than 21,000 materials are available publicly via a dedicated web app.

    Growth and characterization of α-Sn thin films on In- and Sb-rich reconstructions of InSb(001)

    α-Sn, the inversion symmetric analogue of HgTe, can be tuned through various topologically non-trivial phases by a combination of strain and/or confinement effects. In addition, thin films of α-Sn have demonstrated very efficient spin-charge conversion. However, α-Sn thin films grown on InSb have been plagued by heavy incorporation of the p-type dopant indium. To better study and make use of the topological phases in α-Sn, this indium doping must be minimized. The authors realize this reduction by tuning the surface reconstruction of InSb(001) on which molecular beam epitaxy growth of α-Sn is initiated. The low indium doping is verified by both photoemission and magnetotransport measurements. The accessibility of the surface Dirac node in angle-resolved photoemission spectroscopy—made possible by the substrate preparation procedure—allows direct measurements of the effect of confinement and epitaxial strain on the topological phase in this system.

    Confinement of magnetic solitons and edge states in a van der Waals material: FeOCl

    This paper reports that domain-wall-like modes govern the magnetic response of the van der Waals material FeOCl. Due to boundaries, these excitations condense into an unconventional magnetic order with a diffusional dynamics as probed by Mössbauer spectroscopy and Raman scattering. These results have implications for a better understanding of fundamental aspects of soliton-like excitations as well as topological magnetism and related information storage. The authors highlight that the observed phenomenology and proposed condensation of solitons into topological edge states is a generic feature of non-linear systems with confinement.
