Abstract
The results of studying the effect of temperature and magnetic field on the relaxation of the thermo-optical signal in semiconductor samples with different electronic spectra n-Ge, n-InSb, ZnSe:Ni are presented. The results were obtained using a two-beam fiber-optic “pump–probe” method with a Fabry–Perot interferometer in the temperature range from 4.2 to 300 K with the application of a magnetic field up to 8 T. The significant change of behavior of reflected probing beam with wavelength of 1530 nm was found after the action of a pump pulse for the sample of n-Ge at temperatures below 30 K and a field induction of more than 2 T. This phenomenon is caused by transformation of electronic structure.
