Optical studies of as-deposited and annealed Cu7GeS5I thin films
Cu7GeS5I thin films were obtained by non-reactive radio frequency magnetron sputtering onto silicate glass substrates. Optical transmission spectra of as-deposited and annealed Cu7GeS5I thin films were measured in the temperature interval 77–300 K. The temperature behaviour of Urbach absorption edge...

| Summary: | Cu7GeS5I thin films were obtained by non-reactive radio frequency magnetron sputtering onto silicate glass substrates. Optical transmission spectra of as-deposited and annealed Cu7GeS5I thin films were measured in the temperature interval 77–300 K. The temperature behaviour of Urbach absorption edge and dispersion of refractive index for as-deposited and annealed Cu7GeS5I thin films was analyzed. Influence of annealing on the optical parameters and disordering processes in Cu7GeS5I thin films was studied. |
