Direct observation of the electronic structure of even-layer puckered SnTe monolayer films on graphene
Satoru Ichinokura, Shunsuke Tsuda, Kiyohisa Tanaka +1
We report a direct observation of the electronic structure of monolayer SnTe on graphene by angle-resolved photoemission spectroscopy. By combining low-energy electron diffraction,…
Two-dimensional superconductivity of the Ca-intercalated graphene on SiC: vital role of the interface between monolayer graphene and the substrate
Haruko Toyama, Ryota Akiyama, Satoru Ichinokura +10
Ca-intercalation has opened a way for superconductivity in graphene on SiC. However, the atomic and electronic structures being critical for superconductivity are still under discu…
Van Hove Singularity and Lifshitz Transition in Thickness-Controlled Li-Intercalated Graphene
S. Ichinokura, M. Toyoda, M. Hashizume +8
We demonstrate a new method to control the Fermi level around the van Hove singularity (VHS) in Li-intercalated graphene on the SiC substrate. By angle-resolved photoemission spect…
Two-dimensional conducting layer on SrTiO surface induced by hydrogenation
Y. Takeuchi, R. Hobara, R. Akiyama +5
We found that a surface state induced by hydrogenation on the surface of SrTiO(001) (STO) did not obey the rigid band model, which was confirmed by in situ electrical resisti…
Efficient Edelstein effects in one-atom-layer Tl-Pb compound
Y. Shiomi, K. T. Yamamoto, R. Nakanishi +5
We have investigated direct and inverse Edelstein effects in a one-atom-layer Tl-Pb compound with a large Rashba-type spin splitting. In spin pumping experiments at room temperatur…
Berry phase shift from 2 to in Bilayer graphene by Li-intercalation and sequential desorption
Ryota Akiyama, Yuma Takano, Yukihiro Endo +4
We have found that the Berry phase of bilayer graphene becomes from 2 estimated by Shubnikov-de Haas oscillations when the A-B stacked pristine bilayer graphene experiences the…
Shubnikov-de Haas oscillations in p and n-type topological insulator (BiSb)Te
Ryota Akiyama, Kazuki Sumida, Satoru Ichinokura +4
We show Shubnikov-de Haas oscillations in topological insulator (BiSb)Te films whose carrier type is p-type (x = 0.29, 0.34) and n-type (x = 0.42). The ph…
Direct Observation of Superconductivity in Calcium-Intercalated Bilayer Graphene by in situ Electrical Transport Measurements
S. Ichinokura, K. Sugawara, A. Takayama +2
We report the superconductivity in Ca-intercalated bilayer graphene CCaC, the thinnest limit of Ca graphite intercalation compound. We performed \textit{in situ} electrical…
