Description: |
Pb 1 -x Sn x Te is a topological crystalline insulator system with an even number of band Dirac cone at 001,110 and 111 orientations, which represent a trivial system under Kane Mele classification. However, in the past few years, the topological surface states feature in Pb 1 -x Sn x Te that protected by mirror symmetry drew attention. In contrast to Kane Mele’s topological material that protects by time-reversal symmetry. Pb 1 -x Sn x Te system has a crystal structure phase transition that can drive the topological features of the system. A systematic study on the energy band gap versus temperature and composition shows an interesting regime at x = (0.3–0.7) and T = 70–130 K. (i.e. the topological crystalline insulator regime, phase transition regime). In this paper, we focused on how the following parameters (energy bandgap, temperature T, composition x ) connect by three stander models. |
