Abstract
Physicochemical transformations that take place in thin nanocrystalline layers of silicon carbonitride as a result of thermal annealing in vacuum at a temperature of 1173 K are investigated. IR, Raman spectroscopy, XPES, ellipsometry and X-ray analysis are applied to study these physicochemical transformations. It is stated that high-temperature annealing of the silicon carbonitride films helps decreasing the amorphous constituent of the film, increasing the density and size of nanocrystals incorporated in the film.
