Abstract

We have investigated the photoconductivity in the linear chain compound K0.3MoO3. The experiments were performed at T = 4.2 K using pulsed infrared laser beam with photon energy corresponding to the single particle gap. The electric field dependence of the observed photocurrent suggests that the optically excited electrons initiate the sliding of the charge density wave condensate, and the current of the collective mode dominates over any single particle contribution. We discuss the role of the electrostatic screening in this mechanism and give an estimation of the efficiency for a photon to excite an electron across the gap.
