Abstract
The current study focused on the impact of arsenic additions on the mechanical, and electrical properties of binary As-Se glasses. Different elastic parameters such as micro-hardness (H), Poisson's ratio (σ), Young (Y)-, and bulk (K)-moduli) as well as Debye temperature (TD) for As-Se glasses were determined based on the measured values of the ultrasonically speeds (transfer, vl, and shear, vs). The activation energies for electrical (ΔEdc) and for thermoelectrical conduction (ΔEthermo) of these glassy thin films were investigated as a function of composition. Y, K and ΔEdc were correlated with the glass transition temperature (Tg). The obtained results were discussed in terms of the average coordination number, crosslink density and overall mean bond energy.
•As-Se glasses in the form of bulk and films were prepared.•The elastic moduli for AsxSe1−x glasses have been determined and discussed.•The activation energies for electrical ΔEdc and thermoelectrical ΔEthermo conduction have been estimated.•K, S and DEdc are correlated with the glass transition temperature (Tg).•Thermo-electric measurements stated that, AsxSe1−x glasses are P-type semiconductor.
