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…
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…
Narrow superconducting window in Ni-doped LaFeAsO
Guanghan Cao, Shuai Jiang, Xiao Lin +7
We have studied Ni-substitution effect in LaFeNiAsO () by the measurements of x-ray diffraction, electrical resistivity, magnetic susceptibility, and…
