Title: Photocurrent in a quantum channel with an impurity

The influence of electromagnetic radiation on electron transport in a quantum channel with a single short-range impurity is studied using the generalization of the Landauer-Buettiker method. It is shown that a direct photocurrent is induced in the system in the case of asymmetric impurity location. The dependence of the photocurrent on the electron chemical potential, impurity location, and radiation frequency is studied.
