摘要
The specific features of the formation of concentration inhomogeneities in crystals grown by the Czochralski method (GaSb:Te, Ge:Ga) and by the Bridgman method (Y3Al5O12:Nd, ZnGeP2, GaSb:Te, Ge:Ga) are analyzed. Digital processing of growth striation (GS) images showed the presence of strict periodicity in the GS distribution along the boule length for the Czochralski-grown crystals (rotational GSs) and the absence of systematic GS distribution for the crystals grown by the Bridgman method. Possible reasons for the observed regularities of variation in crystal composition are discussed.
