Robust charge-density wave strengthened by electron correlations in monolayer 1T-TaSe2 and 1T-NbSe2
Yuki Nakata, Katsuaki Sugawara, Ashish Chainani +11
Combination of low-dimensionality and electron correlation is vital for exotic quantum phenomena such as the Mott-insulating phase and high-temperature superconductivity. Transitio…
Observation of inverted band structure in topological Dirac-semimetal candidate CaAuAs
Kosuke Nakayama, Zhiwei Wang, Daichi Takane +13
We have performed high-resolution angle-resolved photoemission spectroscopy of ternary pnictide CaAuAs which is predicted to be a three-dimensional topological Dirac semimetal (TDS…
Dimensionality reduction and band quantization induced by potassium intercalation in 1-HfTe
Y. Nakata, K. Sugawara, A. Chainani +9
We have performed angle-resolved photoemission spectroscopy on transition-metal dichalcogenide 1-HfTe to elucidate the evolution of electronic states upon potassium (K) depo…
Monolayer VTe2: Incommensurate Fermi surface nesting and suppression of charge density waves
Katsuaki Sugawara, Yuki Nakata, Kazuki Fujii +4
We investigated the electronic structure of monolayer VTe2 grown on bilayer graphene by angle-resolved photoemission spectroscopy (ARPES). We found that monolayer VTe2 takes the oc…
Pseudogap, Fermi arc, and Peierls-insulating phase induced by 3D-2D crossover in monolayer VSe2
Yuki Umemoto, Katsuaki Sugawara, Yuki Nakata +2
One of important challenges in condensed-matter physics is to realize new quantum states of matter by manipulating the dimensionality of materials, as represented by the discovery…
Observation of band crossings protected by nonsymmorphic symmetry in the layered ternary telluride Ta3SiTe6
Takafumi Sato, Zhiwei Wang, Kosuke Nakayama +8
We have performed angle-resolved photoemission spectroscopy of layered ternary telluride Ta3SiTe6 which is predicted to host nodal lines associated with nonsymmorphic crystal symme…
