Optically detecting the edge-state of a three-dimensional topological insulator under ambient conditions by ultrafast infrared photoluminescence spectroscopy
Ultrafast infrared photoluminescence spectroscopy was applied to a three-dimensional topological insulator TlBiSe(2) under ambient conditions. The dynamics of the luminescence exhibited bulk-insulating and gapless characteristics bounded by the bulk band gap energy. The existence of the topologicall...
