Structure-property relationships in critically connected (GeTe)(AsSe) glasses.

Thermal, optical, mechanical and structural studies were carried out on glasses in the pseudo-binary joint GeTe-AsSe prepared by a melt quenching method. (GeTe)(AsSe) glasses in the entire composition range of 0 ≤ ≤ 100 have an average coordination number () = 2.4, where the glass forming ability is found to be maximum.

Structural transformation and phase change properties of Se substituted GeTe.

GeTeSe (0 ≤ x ≤ 1.0) alloys have been prepared both in bulk and thin film forms to study the effect of selenium (Se) substitution for tellurium (Te) on the phase change properties. It is observed that with increasing Se substitution in GeTe, the structure transforms from rhombohdral structure to orthorhombic structure.
