Weak topological insulators in PbTe/SnTe superlattices
It is desirable to realize topological phases in artificial structures by engineering electronic band structures. In this paper we investigate (PbTe)[subscript m](SnTe)[subscript 2n−m] superlattices along the [001] direction and find a robust weak topological insulator phase for a large variety of l...
