Abstract

Far infrared (FIR) high-power pulsed laser radiation incident normal to the surface of GaAs/metal heterostructures with a self-consistent tunnel Schottky barrier gives rise to a change in the tunnel conductance. We show that the observed photoresistive effects are caused by ponderomotive forces of the radiation field on the free electron plasma in the junctions. At low power levels the change of ...
