摘要

The aim of this study is to investigate the nonlinearity of refraction in nanostructured silicon carbide films depending on their structural features (synthesis conditions for such films, substrate temperature during their deposition, concentration of the crystalline phase in the film, Si/C ratio of atomic concentrations in the film, and size of SiC nanocrystals formed in the film). The corresponding dependences are obtained, as well as the values of nonlinear-optical third-order susceptibility χ~((3))(ω ω -ω ω) for various silicon polytypes (3C, 21R, and 27R) which exceed the value of χ~((3)) in bulk silicon carbide single crystals by four orders of magnitude.
