Physical properties of Se90-xIn10Sbx glassy system
Abdelhamid BADAOUI,Maamar BELHADJI,Mostefa GHAMNIA 한양대학교 세라믹연구소 2016 Journal of Ceramic Processing Research Vol.17 No.4
The effect of antimony (Sb) addition in SeIn glassy system is theoretically studied, and important physical properties, such asaverage coordination number, lone pair electrons, fragility parameter, heat of atomization, mean bond energy and optical bandgap are evaluated in addition to thermal stability. The values of average coordination number and heat of atomization werefound to increase with increasing Sb content, while the other properties were in decrease. By adding more Sb atoms, the glassysystem becomes less stable thermally. According to the number of zero-frequency mode per atom, which was in decrease, thePhillips’-Thorpe threshold cannot be realized for the considered glassy system.
