Chemical surface deposition of CdS thin films from CdI2 aqueous solution

For the first time using CdI2 solution CdS films on glass and ITO coated glass substrates were produced by the method of layerwise chemical surface deposition (ChSD). CdS thin films with the widths from 40 nm to 100 nm were obtained for windows in solar cells based on CdS/CdTe heterojunctions. Changes of the structural and optical properties of CdS films due to air annealing are shown. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/910

Synthesis and Electrical Properties of Ag₈SnSe₆ Argyrodite Thin Films

The synthesis of Ag8SnSe6 argyrodite thin films with thickness 500 nm by selenization of Ag-Sn film at 480 oC was carried out. Thin films were investigated by X-ray diffraction. Ternary Ag8SnSe6 synthesized in orthorhombic structure with the lattice parameters a = 7.9081(6) Å, b = 7.8189(7) Å, c = 11.0464(9) Å, V = 683.03(10) Å3. Resistive switching cell based on Ag8SnSe6 argyrodite with silver and graphite electrodes was fabricated. Electrical properties of cell were investigated using impedance spectroscopy and cyclic voltammetry. Cell structure and process in this cell were modeled by electric equvivalent circuit. Resistive switching phenomena in Ag/Ag8SnSe6/C cell at certain applied voltage were demonstrated.
