Compositional dependence of the optical properties of amorphous antimony selenide thin films using transmission measurements

Thickness dependence of structural and optical properties of cadmium iodide thin films

“…This redshift indicates that, the thickness of the deposited films directly affects the optical transmittance spectra and, consequently, affects the optical band gap of the deposited films. The envelope method is used by many researchers [18][19][20][21] for calculating the refractive index and film thickness. This method can be achieved via recording the envelopes around the interference maxima and minima of the transmittance spectra [22][23][24].…”

Effect of film thickness on microstructure parameters and optical constants of CdTe thin films

“…Different authors [33][34][35] have suggested different values of m for different glasses, m = 2 for most amorphous semiconductors (indirect transition) and m = 1/2 for most of crystalline semiconductors (direct transition). In the case of different thickness of polycrystalline of CdTe thin films the direct transitions are valid.…”

“…The refractive index was determined using Swanepoel's method (method of recording envelopes around the interference maxima and minima of the transmittance spectra [28,29,35]. Fig.…”

Raman spectroscopic study of SbxSe100−x phase-separated bulk glasses

“…However, using splat-cooling techniques, foils of glasses were prepared for Sb content up to 50 at.% [5]. Despite the above-mentioned shortcomings the non-crystalline phases of antimony selenides meet a number of applications in view of their interesting optical properties [6] and could be potentially used as phase change non-volatile memory materials [7].…”
