Alloy broadening of the transition to the non-trivial topological phase of Pb_{1-x}Sn_{x}Te

A. Lusakowski, P. Boguslawski, T. Story

Transition between the topologically trivial and non-trivial phase of Pb_{1-x}Sn_{x}Te alloy is driven by the increasing content $x$ of Sn, or by the hydrostatic pressure for $x<0.…
