Type-I and Type-II Saddle Points and a Topological Flat Band in a Bi-Pyrochlore Superconductor CsBi2
Yusei Morita, Yongkai Li, Yu-Hao Wei +12
The divergence of the electron density of states (DOS) plays an important role in enhancing many-body interactions and inducing various quantum phases in low-dimensional systems. H…
Giant Rashba splitting in PtTe/PtTe heterostructure
Runfa Feng, Yang Zhang, Jiaheng Li +11
Achieving a large spin splitting is highly desirable for spintronic devices, which often requires breaking of the inversion symmetry. However, many atomically thin films are centro…
Unusual temperature dependence of the band structure associated with local atomic distortion in monolayer 1T'-WTe2
Ryuichi Ando, Katsuaki Sugawara, Tappei Kawakami +4
The ground state of monolayer 1T'-WTe2 has been a target of intensive debate on whether or not it is a two-dimensional topological insulator (2D TI) associated with exciton formati…
Selective Fabrication of Monolayer 1H- and 1T'-WTe2
Ryuichi Ando, Katsuaki Sugawara, Tappei Kawakami +2
We selectively fabricated monolayers of octahedral (1H) and distorted trigonal (1T') WTe2 on graphene/SiC(0001) by controlling the substrate temperature during epitaxy. Angle-resol…
Evolution of Band Structure in a Kagome Superconductor Cs(V1-xCrx)3Sb5: Toward Universal Understanding of CDW and Superconducting Phase Diagrams
Shuto Suzuki, Takemi Kato, Yongkai Li +10
Kagome superconductors AV3Sb5 (A = K, Rb, Cs) exhibit a characteristic superconducting and charge-density wave (CDW) phase diagram upon carrier doping and chemical substitution. Ho…
In-situ topotactic chemical reaction for spectroscopies
Tappei Kawakami, Kosuke Nakayama, Katsuaki Sugawara +1
Topotactic chemical reaction (TCR) is a chemical process that transforms one crystalline phase to another while maintaining one or more of the original structural frameworks, typic…
