Abstract. The methods of optical absorption spectroscopy and high-resolution diffractometry have been used to study the influence of microwaves on characteristics of crystalline SiC. Being based on the X-ray analysis data, optical transmission, photoluminescence, and photoluminescence excitation spectra, it has been shown that the microwave treatment leads to a change in the gradient of internal mechanical stresses and an increase in the migration capability of dislocations and, as a result, to redistribution of recombination centers in the sample.
Keywords: microwave radiation, relaxation processes, silicon carbide, optical absorption spectroscopy, high-resolution diffractometry.
