Band structure and topological phases of Pb${}_{1-x-y}$Sn${}_x$Mn${}_y$Te by ab initio calculations

A. Łusakowski, P. Bogusławski, T. Story

The change in the composition of Pb${}_{1-x}$Sn${}_x$Te IV-VI semiconductor or in its lattice parameter can drive a transition from the topologically trivial to the topological crystal…
