Determination of the energy band gap of Bi(2)Se(3)
Despite intensive investigations of Bi(2)Se(3) in past few years, the size and nature of the bulk energy band gap of this well-known 3D topological insulator still remain unclear. Here we report on a combined magneto-transport, photoluminescence and infrared transmission study of Bi(2)Se(3), which u...

description | Despite intensive investigations of Bi(2)Se(3) in past few years, the size and nature of the bulk energy band gap of this well-known 3D topological insulator still remain unclear. Here we report on a combined magneto-transport, photoluminescence and infrared transmission study of Bi(2)Se(3), which unambiguously shows that the energy band gap of this material is direct and reaches E (g) = (220 ± 5) meV at low temperatures. |
