Abstract

Quantum phase transition in topological insulators has drawn heightened attention in condensed matter physics and future device applications. Here we report the magnetotransport properties of single crystalline (Bi0.92In0.08)2Se3. The average mobility of about 1000 cm2/Vs is obtained from the Lorentz law at the low field up to 50 K. The quantum oscillations rise at a field of about 5 T, revealing a high mobility of 1.4*10^4 cm2/Vs at 2 K. The topological Dirac fermions are evident by the nontrivial Berry phase in the Landau Fan diagram. The properties make the (Bi0.92In0.08)2Se3 a promising platform for the investigation of quantum phase transition in topological insulators.
