Bulk band inversion and surface Dirac cones in LaSb and LaBi: Prediction of a new topological heterostructure

Abstract We perform ab initio investigations of the bulk and surface band structures of LaSb and LaBi and resolve the existing disagreements about the topological property of LaSb, considering LaBi as a reference. We examine the bulk band structure for band inversion, along with the stability of sur...
