Measurements of optical properties have been made on alloyed samples of Se and Ge with In prepared under vacuum by quenching the melt into water. The optical transmission spectra of film Se 90 Ge 10Γx In x (x ΒΌ 2, 4 and 6) were measured in the wavelength range 400-2000 nm by spectrophotometer. It is

Different compositions of amorphous Ge 20 Se 80 and Ge 20 Se 75 M 5 (M= Cd, Bi, or Zn) semiconducting films were deposited onto cleaned glass substrates by thermal evaporation method. The interference transmission spectra T(l) at normal incidence for Ge 20 Se 75 M 5 thin films were obtained in the w
The optical properties of as-deposited Ge x Se 92Γx In 8 (x ΒΌ 10, 12.5, 15 and 20 at%) have been studied. Various optical constants have been calculated for the studied compositions. The mechanism of the optical absorption follows the rule of non-direct transition. It was found that, the optical ene
