Influence of Ge addition on the optical properties of As₄₀Se₅₀Ge₁₀ thin film probed by spectroscopy techniques

Role of annealing temperature on optimizing the linear and nonlinear optical properties of As40Se50Ge10 films

“…31,32 In our previous report, we had shown the inuence of Ge addition on the optical properties of As 40 Se 50 Ge 10 thin lms. 33 However, the tuning of linear and non-linear optical constants in thermally evaporated As 40 Se 50 Ge 10 lm by annealing at different temperature including both below and above T g is not yet investigated. The T g for the As-Se-Ge system varies between 150 C to 200 C approximately with low value of Ge%.…”
