Abstract
The optical properties of one-dimensional microcavity based on nanocrystalline SiC (nc-SiC) films containing nanocrystals of cubic and rhombohedric polytypes (R24 and R27, respectively) have been studied. It was revealed that resonance absorption maxima in absorption spectra measured at room temperature varied from 2.17 to 2.79 eV for the nc-SiC films 300–450 thick. To explain the thickness dependence of resonance absorption in the microcavities based on heteropolytypic nc-SiC films, the model of exciton–polariton states in the one-dimensional microcavity based on nanocrystalline SiC film has been proposed.
