  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.
