Abstract :
The oscillations of reflection and transmission coefficients of the probing laser radiation (Shubnikov-de Haas (SdH) effect) in low-dimensional GaAs/AlGaAs structures, containing quantum wells, and in degenerate n-InSb at low temperatures (~2 K) were investigated. The possibility of contactless determination of the transport parameters in semiconductors, based on the observations of SdH oscillations at liquid nitrogen temperature, is discussed
