Structural Evolution in Thin Films of Ag2Te1−xSex (x~0.3) Alloy Prepared by Thermal Evaporation Technique

Ag2Te thin films' structural and optical characteristics as a result of Al doping

“…By using the thermal evaporation method, the Ag 2 Te films were doped with the element (Al) in a ratio of (1%, 1.5%). After determining the atomic percentages, the doping element was deposited on the Ag 2 Te films, and the samples were then placed in an electric furnace at 100 °C for one hour [13].…”

Tuning the nonlinear susceptibility and linear parameters upon annealing Ag60−xSe40Texnanostructured films for nonlinear and photonic applications

“…The compositions are stable glass formers and may be used in the infrared system [41] . The rate of enhancement of transmittance is higher at infrared regions for Ag 2 (Se .3 Te .7 ) thin films and quantum confinement and other factors lead to an increase in band gap and beyond a specific thickness, annealing effect becomes dominant and the band gap is continuously lowered [42] . From the previous studies, it has been seen that the incorporation of Te in Ag-Se system alters different linear and non-linear properties of the material for various optical devices related applications [43] .…”

“…41 The rate of enhancement of transmittance is higher in the infrared regions for Ag 2 (Se .3 Te .7 ) thin films and quantum confinement and other factors lead to an increase in the band gap, and beyond a specific thickness, the annealing effect becomes dominant and the band gap is continuously lowered. 42 From the previous studies, it has been seen that the incorporation of Te into the Ag-Se system alters different linear and non-linear properties of the material for various optical device-related applications. 43 The Ag-Se-Te ternary system is an important thermoelectric material system, and typically, it shows the best thermoelectric performance at low temperatures.…”
