Topological crystalline insulators form a class of semiconductors for which surface electron states with the Dirac dispersion relation are formed on surfaces with a certain crystallographic orientation. Pb Sn Te alloys belong to the topological crystalline phase when the SnTe content exceeds 0.35, w...
