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

Abstract

The present work shows the effect of annealing conditions on the linear and nonlinear optical properties of two-year-old thermally evaporated 800 nm As40Se50Ge10 thin films.

Optimization of different temperature annealed nanostructured CdSe thin film for photodetector applications

“…The n 0 value increased like the linear refractive index (n) as shown in Table 1 which is responsible for the change in nonlinear optical parameters [28].…”

The impact of fluence dependent 120 MeV Ag swift heavy ion irradiation on the changes in structural, electronic, and optical properties of AgInSe2 nano-crystalline thin films for optoelectronic applications

“…Most of the applications of this material are realized in its thin film form. The material modification by various external energy sources like laser irradiation, 20 thermal annealing, 21 γ irradiation, 22 proton irradiation, 23 etc. brings significant changes in their optical as well as structural properties.…”

Investigation of amorphous-crystalline transformation induced optical and electronic properties change in annealed As50Se50 thin films

“…They are basically in non-equilibrium state in their as-prepared condition due to the sudden quenching process (Nordman et al 1998). The various characteristic parameters should be in their stable form while using them for various applications which can be done by thermal annealing at different temperatures (Sahoo et al 2020a), bombarding with energetic ions (Behera et al 2020), laser irradiation (Aparimita et al 2020a), gamma and X-ray irradiation (Sharma et al 2020) and many other suitable techniques. The chalcogenide thin films switched locally by means of structural, optical and electrical parameters upon such treatments and found important applications in optoelectronic devices, solar cells, infrared detectors, optical biosensors, low loss waveguides, optical switches, fibers and many more (Manivannan and Noyel Victoria 2018;Purohit et al 2015;Xu et al 2014;Zhai et al 2016;Anne et al 2009;Sojka et al 2012).…”
