“…Large conductivity increases could be caused by the additions of additives, 10 although conductivities of amorphous semiconductors are generally much less sensitive to nonstoichiometry and the presence of impurities than are those of crystalline semiconductors. Copper is a commonly used dopant for enhancing the conductivities of chalcogenide glasses 11–13 . The major reason is that a large number of copper can be introduced into chalcogenide glasses and the metallic character can usually be increased efficiently.…”

“…In the Raman spectrum, two intense bands develop at 168 and 205 cm −1 and become the main features at x = 2.5 for As 2 Se 3−x Te x (x = 2 for As 3 Se 7−x Te x ) glasses. The Raman band at 205 cm −1 can be attributed to vibrations of Se-Te bonds, as observed in the system Se 1−x Te x [28], or to As-Se vibration in mixed AsSe 3−x Te x units [29,30]. The latter proposition may contribute predominantly to this Raman band.…”

“…The latter proposition may contribute predominantly to this Raman band. The As-Te stretching in tellurium rich AsSe 3−x Te x entities (x ≥ 2) would give rise to the Raman band at 168 cm −1 [29,30]. The presence of Te-Te bonds are not expected from Raman analysis of the spectra which should have a signature at 150-155 cm −1 [28].…”

“…The IR spectrum of the x = 20 glass shows its main band at 220 cm −1 . We attribute the Raman band at 205 cm −1 to vibrations of Se-Te bonds as observed in the system Se 1−x Te x [36] or to As-Se vibration in mixed AsSe 3−x Te x units [37,38]. The strong IR band at 220 cm −1 would be consistent with the formation of mixed AsSe 3−x Te x units, considering that the 3 mode of [AsSe 3/2 ] pyramids is active at 230 cm −1 (Fig.…”
