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.
