Abstract :
Photon drag and photovoltaic response observed in p/sup +//n and n/sup +//p silicon junctions excited by moderated-power-density 10- mu m radiation are discussed. A multistep multiphotonic process through intermediate states located within the energy gap is proposed as the mechanism responsible for the photovoltaic potential.<>
