КІНЕТИЧНІ ЗАКОНОМІРНОСТІ ВИПАРОВУВАННЯ Й КОНДЕНСАЦІЇ ПОКРИТТІВ З CVD-КОМПОЗИТІВ СИСТЕМ ХАЛЬКОШПІНЕЛЬ-ГЕРМАНІЙ

Abstract

Character of thermal evaporation in vacuum and condensation on a substrate of samples of systems chalcospinel MM'₂X₄ (M - Zn, Mn, Eu(II), Yb(II)) - Ge is investigated. Correlation between the rate of condensation and volatility of products of interaction of components of systems is revealed. For the majority of composites mechanical durability of the received coatings exceeds that for coatings from individual compounds. Presence of germanium in a coating promotes an essential growth of its refractive index. The highest values of mechanical durability possess the coatings received from composites with lowest volatility (EuIn₂S₄-Ge, EuIn₂Se₄-Ge).
