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…
Switching of band inversion and topological surface states by charge density wave
N. Mitsuishi, Y. Sugita, M. S. Bahramy +14
Topologically nontrivial materials host protected edge states associated with the bulk band inversion through the bulk-edge correspondence. Manipulating such edge states is highly…
Field-induced spin reorientation in the antiferromagnetic Dirac material EuMnBi revealed by neutron and resonant x-ray diffraction
H. Masuda, H. Sakai, H. Takahashi +7
Field-dependent magnetic structure of a layered Dirac material EuMnBi was investigated in detail by the single crystal neutron diffraction and the resonant x-ray magnetic diffr…
Ferroelectric atomic displacement in multiferroic tetragonal perovskite SrBaMnO
D. Okuyama, K. Yamauchi, H. Sakai +5
We investigate the crystal structure in multiferroic tetragonal perovskite SrBaMnO with high accuracy of the order of 10 Angstrom for an atomic displacem…
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…
Giant enhancement of cryogenic thermopower by polar structural instability in the pressurized semimetal MoTe2
Hidefumi Takahashi, Kento Hasegawa, Tomoki Akiba +3
We found that a high mobility semimetal 1T'-MoTe2 shows a significant pressure-dependent change in the cryogenic thermopower in the vicinity of the critical pressure, where the pol…
