Abstract

We report on the observation of a terahertz radiation-induced photon drag effect in epitaxially grown n- and p-type (Bi1−xSbx)2Te3 three-dimensional topological insulators with different antimony concentrations x varying from 0 to 1. We demonstrate that the excitation with polarized terahertz radiation results in a dc electric photocurrent. While at normal incidence a current arises due to the ...
