Softening Temperature of the Amorphous Cu-As-Se-I System

Softening Temperature of the Amorphous Cu-As-Se-I System A detailed characterization of softening temperatures of a series of samples of the amorphous Cu-As-Se-I system is presented. Previous investigations showed that the most effective mode of erasing optical information stored in this complex quaternary system of chalcogenide amorphous semiconductors (ChAS) is a thermal treatment of the samples at temperatures close to their softening points. On the basis of the results obtained using a range of thermal methods it was possible to determine the interval of the beginning of the softening process of the glass, as well as the coefficient of linear expansion of the samples before and after their softening. Measurements of the temperature dependence of the thin film transparencies enabled the determination of softening temperatures of such types of samples of the investigated system, including the reversibility of the processes determining their transparency properties. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Thermal Analysis and Calorimetry Springer Journals

Abstract

A detailed characterization of softening temperatures of a series of samples of the amorphous Cu-As-Se-I system is presented. Previous investigations showed that the most effective mode of erasing optical information stored in this complex quaternary system of chalcogenide amorphous semiconductors (ChAS) is a thermal treatment of the samples at temperatures close to their softening points. On the basis of the results obtained using a range of thermal methods it was possible to determine the interval of the beginning of the softening process of the glass, as well as the coefficient of linear expansion of the samples before and after their softening. Measurements of the temperature dependence of the thin film transparencies enabled the determination of softening temperatures of such types of samples of the investigated system, including the reversibility of the processes determining their transparency properties.
