Infrared Optical Conductivity of Bulk Bi<sub>2</sub>Te<sub>2</sub>Se

Infrared Optical Conductivity of Bulk Bi<sub>2</sub>Te<sub>2</sub>Se

Mid- and near-infrared measurements reveal that the optical conductivity of the three-dimensional topological insulator, Bi<sub>2</sub>Te<sub>2</sub>Se, is dominated by bulk carriers and shows a linear-in-frequency increase at 0.5 to 0.8 eV. This linearity might be interprete...
