Abstract
Diagnostics of semiconductors by multi-frequency irradiation is a fairly effective way to determine all possible parameters of the samples. It is shown that, when a semiconductor sample cooled to low temperatures is irradiated by multi-frequency electromagnetic radiation, several variants of nonlinear scattering in the crystal plasma are possible. Nonlinear interaction of incident and reflected light waves in the region where the plasma flow velocity is close to the speed of sound can significantly reduce the efficiency of using multi-frequency pumping for deep diagnostics of semiconductor crystals with a narrow band gap at low temperatures.
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
