摘要

In this work, we show that the use of terahertz laser radiation combined with magnetic field provides an opportunity to detect high mobility surface electron states in (Bi1-xInx)2Se3 solid solutions being either in topological insulator (TI) (x 0.06) phase. It is demonstrated that in TI Bi2Se3 the photoelectromagnetic effect amplitude is defined by the number of incident radiation quanta, whereas for TS (Bi0.88In0.12)2Se3 it only depends on the power of a laser pulse irrespective of its wavelength. The possible reasons for such a different behavior may be related to the enhanced thermalization time of the non-equilibrium carriers due to strong damping of electron-electron interaction in TI.
