Observation of topologically protected states at crystalline phase boundaries in single-layer WSe2

Observation of topologically protected states at crystalline phase boundaries in single-layer WSe2

Transition metal dichalcogenides may host exotic topological phases in the two-dimensional limit, but detailed atomic properties have rarely been explored. Here, Ugeda et al. observe edge-states at the interface between a single layer quantum spin Hall insulator 1T′-WSe2 and a semiconductor 1H-WSe2....
