Author(s): A. Dubroka, O. Caha, M. Hronček, P. Friš, M. Orlita, V. Holý, H. Steiner, G. Bauer, G. Springholz, and J. Humlíček We have investigated the optical properties of thin films of topological insulators Bi 2 Te 3 , Bi 2 Se 3 , and their alloys Bi 2 ( Te 1 − x Se x ) 3 on BaF 2 substrates by a combination of infrared ellipsometry and reflectivity in the energy range from 0.06 to 6.5 eV. For the onset of interband absorption in Bi 2 Se 3 , ... [Phys. Rev. B 96, 235202] Published Tue Dec 12, 2017
