Optical properties of amorphous GexSb40− xSe60 (x= 22.5, 25, 27.5, 30 and 32.5 at.%) thin
films prepared by electron beam evaporation have been measured in the visible and near …

Optical constants, dispersion and oscillator parameters of different thicknesses of
amorphous Ge_25Cd_5Se_70 films have been deposited onto glass substrates using …

Zinc selenide (ZnSe) thin films with different thicknesses were evaporated onto glass
substrates using the thermal evaporation technique. X-ray diffraction analysis confirmed that …

The optical band gap and optical constants have been studied as a function of photon
energy for a-Ga x Se100–x thin films (where x× 0, 2.5, 5.0, 7.5 and 10.0) in the wavelength …

The heat transfer in SiO2 is mainly dominated by phonons, but the void defects and
boundary effects in the films cause strong scattering of phonons, resulting in a low thermal …

Some optical properties of AgInSe2 thin films are studied as a function of γ-doses. In order to
determine the optical energy gap Eg, the absorbance spectra of the films of different γ-doses …

The optical properties of a-Ga20Se80− xSbx thin films (where x= 0, 5, 10, 15, and 20) have
been studied. It is found that the optical band gap decreases with increasing Sb component …

Measurements of optical constants (absorption coefficient, refractive index, extinction
coefficient, real and imaginary part of the dielectric constant) have been made on a …

An investigation of the electrical and optical properties of (Ge2S3) 1 (Sb2Se3) 1, Sb2Se3,
and Ge2S3 thin films prepared by thermal evaporation having different thicknesses and …

Thin films of Se1− xTex (x= 0.2, 0.4, 0.6) are deposited on a glass substrate by thermal
evaporation under vacuum. The optical gaps (Eg) are determined from the absorbance and …
