Thermal and photodiffusion of Ag in S-rich Ge– S amorphous films
We have investigated silver diffusion driven by heating or irradiation with light in sulfur-rich Ge–S thin films close to the composition Ge S . Quantitative data regarding the amount of diffused silver has been gathered using Rutherford backscattering 20 80 spectrometry. Thermal diffusion produces films with 35 at.% silver in the glassy matrix at saturation while photodiffusion forms a film wi...
متن کاملEffect of photo-oxidation on the photodiffusion of silver in germanium chalcogenide glasses
We report results on photoinduced changes in Ge-chalcogenide glasses, which occur in ultra high vacuum (UHV) vs. in air. They demonstrate the important role of oxygen that determines the magnitude and the type of the photoinduced effects. To observe photodiffusion without the presence of oxygen, Ag/glass thin films were prepared, subjected to photodiffusion, and chemically analyzed, all within ...
متن کاملEvolution of chemical structure during silver photodiffusion into chalcogenide glass thin films
The change of chemical structure resulting after X-ray and photo-induced silver diffusion into chalcogenide glass (ChG) thin films is monitored by high resolution X-ray photoelectron spectroscopy (XPS). As40S60 and Ge30Se70 thin films, which are based on pyramids and tetrahedral structural units, are investigated as model materials. Survey, core level (As 3d, S 2p, Ge 3d, Ge 2p, Se 3d, Ag 3d5/2...
متن کاملHeterogeneity of Molecular Structure of Ag Photo-Diffused Ge<sub>30</sub>Se<sub>70</sub> Thin Films
Silver photodiffusion in thin Ge30Se70 films is investigated in order to understand the structure forming in the Ge-Se host after introduction of Ag in it. Optical micrographs point towards formation of homogeneous films after deposition of the Ge-Se material on glass substrate. This structure changes and occurrence of heterogeneous regions is imaged after Ag is introduced into the Ge-Se host. ...
