Amorphous As50Se50 and As50Se40Te10 thin films were prepared on glass substrates by using thermal evaporation method. The transmission spectra T (λ) of the films at normal incidence were measured in the wavelength range 400–1100 nm. A straightforward analysis proposed by Swanepoel based on the use of the maxima and minima of the interference fringes has been used to drive the refractive index(n) and...
In the present report, we have demonstrated the combine effect of deposition and photo diffusion of Te into As50Se50 chalcogenide thin films. The influence of Te deposition onto As50Se50 layer has modified the optical parameters. The thermally evaporated Te/As50Se50 bilayer film is irradiated with near bandgap laser light. The optical and structural property of Te/As50Se50 bilayer film under the influence...
