Physical characteristics, band-gap and glass-transition temperature estimations of (CdTe)100−x(SbSe)x glasses

Abstract

Given the importance of (CdTe) and (SbSe) properties, one can presume exceptional applications of (CdTe)(100-x)(SbSe)(x) compounds. Therefore, diverse physicochemical characteristics were investigated. The overall number of coordination (CN), number of constraints (N-c), heat of atomization (H-a), cohesive energy (CE), and lone-pair electrons (LPE) of (CdTe)(100-x)(SbSe)(x) chalcogenide glasses were studied using the known chemical bond approach. CN and N-c diminished when the amount of SbSe was increased, whereas CE increased due to the decrease in Cd-Cd homo-polar bonds. The band gap (E-g) was assessed and found to diminish with SbSe expansion. A good agreement was found between the E-g assessments and previous experimental studies. The conduction and valence band positions were also determined. The glass-transition temperature (T-g) was assessed and found to diminish with SbSe expansion.
