Polarity-dependent charge-density wave in a kagome superconductor CsV3Sb5
Takemi Kato, Yongkai Li, Kosuke Nakayama +7
Polar surface and interface play a pivotal role for realizing exotic properties of materials, and a search for such polar states is of crucial importance for expanding materials' f…
Carrier Injection and Manipulation of Charge-Density Wave in Kagome Superconductor CsV3Sb5
Kosuke Nakayama, Yongkai Li, Takemi Kato +5
Kagome metals AV3Sb5 (A = K, Rb, and Cs) exhibit a unique superconducting ground state coexisting with charge-density wave (CDW), whereas how these characteristics are affected by…
Electronic states of multilayer VTe2: quasi-one-dimensional Fermi surface and implications to charge-density waves
T. Kawakami, K. Sugawara, T. Kato +4
We have performed angle-resolved photoemission spectroscopy on epitaxial VTe2 films to elucidate the relationship between the fermiology and charge-density waves (CDW). We found th…
Multiple Energy Scales and Anisotropic Energy Gap in the Charge-Density-Wave Phase of Kagome Superconductor CsV3Sb5
Kosuke Nakayama, Yongkai Li, Takemi Kato +5
Kagome metals AV3Sb5 (A = K, Rb, and Cs) exhibit superconductivity at 0.9-2.5 K and charge-density wave (CDW) at 78-103 K. Key electronic states associated with the CDW and superco…
Modulation of Dirac electrons in epitaxial Bi2Se3 ultrathin films on van-der-Waals ferromagnet Cr2Si2Te6
Takemi Kato, Katsuaki Sugawara, Naohiro Ito +7
We investigated the Dirac-cone state and its modulation when an ultrathin film of topological insulator Bi2Se3 was epitaxially grown on a van-der-Waals ferromagnet Cr2Si2Te6 (CST)…
