Transport properties of In_xSn_1−xTe nanostructures — •Mengmeng Bai, Fan Yang, Zhiwei Wang, and Yoichi Ando — Institute of Physics II, Cologne, Germany

SnTe is a three-dimensional topological crystalline insulator. It is known that superconductivity can be induced in SnTe by indium doping, making In_xSn_1−xTe a promising platform for searching for topological superconductivity. Here we present our study on superconducting In_xSn_1−xTe nanostructures. In_xSn_1−xTe nano-plates and nanowires were grown via vapor-transport method. After the growth, they were fabricated into devices and then measured in a cryostat. A sharp superconducting transition was observed in all devices. Point contact spectroscopy was also taken at low temperatures. The preliminary results are presented and discussed.
