Abstract

Experimental results related to the research of photocurrent vibrations induced by IR light in silicon with quantum dots are presented. It is shown that the large amplitude of the vibrations (up to 1 A) and the depth of the modulation (∼100%) observed in the experiment cannot be explained in the framework of the S.G. Kalashnikov Theory. To explain the observed photocurrent vibrations, the self-organized quantum dots, which possess anomalously large asymmetric capture cross sections for charge carriers, are used.
