Influence of the Introduction of Copper into Amorphous $As_2Se_3$ Matrix on Its Thermal and Structural Characteristics

This paper describes the results of the determination of some thermal and structural parameters of glasses from the $Cu_{x}(As_2Se_3)_{100-x}$ system for x=0, 1, 5, 10 and 15 at.%. Based on the differential scanning calorimetry curves taken at different heating rates, glass transition temperature $T_{g}$, onset temperature of crystallization $T_{onset}$, and melting temperature $T_{m}$ of crystalline units formed are determined. The values of activation energy $E_{g}$ of glass transition process are calculated. These characteristic temperatures served as the basis for the calculation of the parameters of thermal stability of the glasses towards crystallization.
