Observation of unoccupied states of SnTe(111) using pump-probe ARPES measurement
A IV-VI compound SnTe is proposed to be a topological crystalline insulator (TCI), and the band structures have been studied by using angle-resolved photoemission spectroscopy (ARPES). However, the topological surface states (TSSs) that hallmark the nontrivial topology disperse mostly in the unoccup...
