Dependence of compositional profile and structural perfection of CdxHg1-xTe graded-gap films on its growing conditions

Abstract

Physical-chemical processes of CdxHg1-xTe graded structures (GSS) growing by evaporation condensation- diffusion method on CdTe substrates from HgTe source were analyzed. GSS were melted to the necessary depth and after crystallization were annealed in mercury vapor in order to obtain CdxHg1-xTe structure-perfect epitaxial layers of given composition.
