Superconductivity and non-metallicity induced by doping the topological insulators Bi2Se3 and Bi2Te3

Y. S. Hor, J. G. Checkelsky, D. Qu +2

We show that by Ca-doping the Bi2Se3 topological insulator, the Fermi level can be fine tuned to fall inside the band gap and therefore suppress the bulk conductivity. Non-metallic…
