Full superconducting gap in the doped topological crystalline insulator, Sn${}_{0.6}$In${}_{0.4}$Te

L. P. He, Z. Zhang, J. Pan +3

The thermal conductivity of the doped topological crystalline insulator, Sn${}_{0.6}$In${}_{0.4}$Te superconducting single crystal with $T_c=$ 4.1 K, was measured down to 50 mK. It is…
