Abstract

We report on the observation of a terahertz radiation-induced photon drag effect in epitaxially grown nand p-type (Bi1-xSbx)(2)Te-3 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 ...
