Basov We have investigated the electronic structure and carrier dynamics of the topological insulator Bi 2−x Sb x Te 3−y Se y , for x=0.5,y=1.3 and x=1,y=2, using infrared spectroscopy. Our results show that both of these BSTS alloys are highly insulating in the bulk, with analysis of the infrared data indicating... [Phys. Rev. B 91, 165202] Published Thu Apr 16, 2015
