Phase diagram of Sn1-xInxTe - a Topological Superconductor candidate

The superconductor Sn1−xInxTe is a doped topological crystalline insulator and has become important as a candidate topological superconductor, but its superconducting phase diagram is poorly understood. By measuring about 50 samples of high-quality, vapor-grown single crystals, we found that the dependence of the superconducting transition temperature Tc on the In content x presents a qualitative change across the critical doping xc  3.8%, at which a structural phase transition takes place.
