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…
Observation of Two-Dimensional Bulk Electronic States in a Superconducting Topological Insulator Heterostructure Cux(PbSe)5(Bi2Se3)6: Implications for Unconventional Superconductivity
K. Nakayama, H. Kimizuka, Y. Tanaka +6
We have performed angle-resolved photoemission spectroscopy (ARPES) on Cux(PbSe)5(Bi2Se3)6 (CPSBS; x = 1.47), a superconductor derived from a topological insulator heterostructure,…
Spin Polarization of Gapped Dirac Surface States Near the Topological Phase Transition in TlBi(S1-xSex)2
S. Souma, M. Komatsu, M. Nomura +6
We performed systematic spin- and angle-resolved photoemission spectroscopy of TlBi(S1-xSex)2 which undergoes a topological phase transition at x ~ 0.5. In TlBiSe2 (x = 1.0), we re…
Direct Observation of the Topological Surface States in Lead-Based Ternary Telluride Pb(Bi1-xSbx)2Te4
S. Souma, K. Eto, M. Nomura +5
We have performed angle-resolved photoemission spectroscopy on Pb(Bi1-xSbx)2Te4, which is a member of lead-based ternary tellurides and has been theoretically proposed as a candida…
Electronic structure of optimally doped pnictide BaKFeAs: a comprehensive ARPES investigation
H. Ding, K. Nakayama, P. Richard +13
We have conducted a comprehensive angle-resolved photoemission study on the normal state electronic structure of the Fe-based superconductor BaKFeAs. We hav…
