Enhancing thermopower and Nernst signal of high-mobility Dirac carriers by Fermi level tuning in the layered magnet EuMnBi
Keigo Tsuruda, Kento Nakagawa, Masayuki Ochi +5
Dirac/Weyl semimetals hosting linearly-dispersing bands have received recent attention for potential thermoelectric applications, since their ultrahigh-mobility carriers could gene…
Epitaxial stabilization of SrCuO with infinite CuO layers
Hiroshi Takatsu, Masayuki Ochi, Naoya Yamashina +4
We report the epitaxial thin film synthesis of SrCuO with infinitely stacked CuO layers composed of edge-sharing CuO square-planes, using molecular beam epitaxy…
Quantifying the stability of the anion ordering in SrVOH
Masayuki Ochi, Kazuhiko Kuroki
We investigate a text-book mixed-anion compound SrVOH using first-principles calculation, to theoretically pin down the factors that stabilize its anion ordering. We find that…
Material design with the van der Waals stacking of bismuth-halide chains realizing a higher-order topological insulator
Ryo Noguchi, Masaru Kobayashi, Zhanzhi Jiang +28
The van der Waals (vdW) materials with low dimensions have been extensively studied as a platform to generate exotic quantum properties. Advancing this view, a great deal of attent…
Large Enhancement of Thermoelectric Efficiency Due to a Pressure-Induced Lifshitz Transition in SnSe
T. Nishimura, H. Sakai, H. Mori +10
Lifshitz transition, a change in Fermi surface topology, is likely to greatly influence exotic correlated phenomena in solids, such as high-temperature superconductivity and comple…
Comparative first-principles study of antiperovskite oxides and nitrides as thermoelectric material: multiple Dirac cones, low-dimensional band dispersion, and high valley degeneracy
Masayuki Ochi, Kazuhiko Kuroki
We perform a comparative study on thermoelectric performance of antiperovskite oxides O and nitrides N ( Ca, Sr, Ba; Ge, Sn, Pb; As, Sb, Bi) by mea…
