Robust midgap states in band-inverted junctions under electric and magnetic fields
Several IV–VI semiconductor compounds made of heavy atoms, such as Pb1−xSnxTe, may undergo band-inversion at the L point of the Brillouin zone upon variation of their chemical composition. This inversion gives rise to topologically distinct phases, characterized by a change in a topological invarian...
