Ag-photodoping in Ge-chalcogenide amorphous thin films—Reaction products and their characterization

We make a brief review on the effect of silver photodiffusion in Ge-chalcogenide glasses and report some of our recent results in this aspect. Using Raman spectroscopy and X-ray diffraction analysis we demonstrate that the hosting backbone undergoes depletion in chalcogen due to the specific conditions of photodiffusion and the diffusion products are silver chalcogenides. While in the Ge–Se sys...

The Li Insertion/Extraction Characteristics of Amorphous Silicon Thin Films

Amorphous hydrogenated silicon (a-Si:H) is known to be a perspective material for negative electrodes of modern lithium-ion batteries. The electrochemical lithium insertion into thin-film a-Si:H electrodes is studied using chronopotentiometry, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The electrodes were grown on stainless-steel substrates by glow discharge at t...
