Electrochemical synthesis and superconducting phase diagram of Cu_xBi2Se3
M. Kriener, Kouji Segawa, Zhi Ren +4
The superconducting Cu_xBi_2Se_3 is an electron-doped topological insulator and is a prime candidate of the topological superconductor which still awaits discovery. The electrochem…
Observation of Dirac Holes and Electrons in a Topological Insulator
A. A. Taskin, Zhi Ren, Satoshi Sasaki +2
We show that in the new topological-insulator compound Bi_{1.5}Sb_{0.5}Te_{1.7}Se_{1.3} one can achieve a surfaced-dominated transport where the surface channel contributes up to 7…
Breakdown of the universal Josephson relation in spin ordered cuprate superconductors
A. A. Schafgans, C. C. Homes, G. D. Gu +3
We present \emph{c} axis infrared optical data on a number of Ba, Sr and Nd-doped cuprates of the LaCuO (La214) series in which we observe significant deviations from t…
Bulk superconducting phase with a full energy gap in the doped topological insulator Cu_xBi_2Se_3
M. Kriener, Kouji Segawa, Zhi Ren +2
The superconductivity recently found in the doped topological insulator Cu_xBi_2Se_3 offers a great opportunity to search for a topological superconductor. We have successfully pre…
Direct Measurement of the Out-of-Plane Spin Texture in the Dirac Cone Surface State of a Topological Insulator
S. Souma, K. Kosaka, T. Sato +6
We have performed spin- and angle-resolved photoemission spectroscopy of Bi2Te3 and present the first direct evidence for the existence of the out-of-plane spin component on the su…
