Effect of Silver content on the Optical and Other Physical Characteristics of Ge-Se Glass System

Abstract

The effect on the optical and other physical properties with the addition of Ag content, viz, T_g, <E>, H_s, <r_eff> , Z, N_con, L, ΔE_g and energetic parameter A of Ge_30-xSe₇₀Ag_x (x = 0, 5, 10, 15, 20 at %) glassy alloy have been examined theoretically. The relationship between the Tg and has been estimated by using Tichy-Ticha approach. The relationship between ΔEg and chemical composition has been discussed in terms of the Hs and Z. In order to correlate the optical parameter (ΔEg) with film composition we used the energetic parameter (A). It has been found that , Hs, (ΔEg), Tg, decreases whereas deviation of stoichiometry R, Ncon and the energetic parameter A, increases with increasing Ag content in Ge-Se-Ag system.
