Abstract

The influence of light- or thermo-induced interdiffusion on optical and electrical parameters of a-Se/As2S3, As0.2S0.8/As0.2Se0.8, Se0.6Te0.4/As2S3, As0.06Se0.94/Se0.8Te0.2 nanolayered structures was investigated. Correlations between the indirect results on interdiffusion (the sign and value of optical absorption edge shift, the changes of photo- and dark conductivity) and the direct results of X-ray diffraction measurements of the periodicity in the multilayer provide additional possibilities of investigations of diffusion processes, structural stability in light sensitive multilayers with nano-scale periodicity..
