Weiss, and S. D. Ganichev We report on the observation of a circular photogalvanic current excited by terahertz laser radiation in helical edge channels of two-dimensional (2D) HgTe topological insulators (TIs). The direction of the photocurrent reverses by switching the radiation polarization from a right-handed to a left-h… [Phys. Rev. B 95, 201103(R)] Published Mon May 08, 2017
