Superconductivity in the doped topological insulator Cu${}_x$Bi${}_2$Se${}_3$ under high pressure

T. V. Bay, T. Naka, Y. K. Huang +3

We report a high-pressure single crystal study of the topological superconductor Cu${}_x$Bi${}_2$Se${}_3$. Resistivity measurements under pressure show superconductivity is depressed smo…
