Abstract:
We show theoretically that absorption of polarized light in chiral conducting surface states of topological insulators results in electric current. The direction of current is determined by light polarization and the magnitude of the current is controlled by radiative recombination. We deduce an expression for the current subject to the external radiation intensity W to characteristic intensity W0 ratio.
