Experimental Observation of Dirac-like Surface States and Topological Phase Transition in Pb[subscript 1-x]Sn[subscript x]Te(111) Films

Experimental Observation of Dirac-like Surface States and Topological Phase Transition in Pb[subscript 1-x]Sn[subscript x]Te(111) Films

The surface of a topological crystalline insulator (TCI) carries an even number of Dirac cones protected by crystalline symmetry. We epitaxially grew high-quality Pb[subscript 1−x]Sn[subscript x]Te(111) films and investigated the TCI phase by in situ angle-resolved photoemission spectroscopy. Pb[sub...
