Abstract: The relaxation behavior in the topological insulator (TI) Bi0.5Sb1.5Te3 has been investigated using 125Te nuclear magnetic resonance spectroscopy. We systematically investigate the spin–lattice relaxation rate (1/T1) in bulk electronic states with varying particle sizes. By… read more here.

Abstract: High quality thin films of the topological insulator (Bi0.4Sb0.6)2Te3 have been deposited on SrTiO3 (111) by molecular beam epitaxy. Their electronic structure was investigated by in situ angleresolved photoemission spectroscopy and in situ scanning tunneling… read more here.
