Effect of microwave radiation on optical transmission spectra in SiO₂/SiC structures

Abstract

We investigated the effect of microwave radiation on absorption spectra (in 400-800 nm range) and curvature radius of SiO₂/SiC structures obtained using traditional thermal oxidation in water vapor at the temperature of 1373 К and rapid thermal annealing in dry oxygen at 1273 К. From an analysis of the sample optical density and radius of curvature variations with total duration of microwave action, we concluded that the structures obtained using rapid thermal annealing are more stable against microwave action.
