Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the present work, preparation of high quality transparent conductive SnO2 thin films by post-oxidation of vacuum evaporated tin, on quartz and silicon substrates is presented. The oxidation was achieved in a short time (90 sec) which is known as rapid thermal oxidation (RTO). Many growth parameters have been considered to specify the optimum conditions, namely, oxidation temperature and oxidation time. Optical, electrical and structural properties of SnO2 films are investigated and analyzed extensively with respect to growth conditions. After obtaining the best results for the preparation of a film. The film was used for the manufacture of MIS devices and for comparison: two types of silicon substrates were used: (n-type and p-type). The optical properties of SnO2 films revealed that the optical band gap is 3.54 eV at optimum condition. The transmission rate of SnO2 films was high (95%) which was reduced with the reduction of oxidation time, while the electrical properties of undoped SnO2 films confirm that these films are n-type and highly conductive. The electrical resistivity was found to be very sensitive to film thickness and substrate temperature. 124 pp. Englisch.…

Neuware -ZnO,TiO2 and ZnO:TiO2-x) nanocomposite with various concentration x=(20, 30, 40, 50)% were prepared using chemical spray, hydrothermal deposition method in which the films were deposited on glass slides,p-types porous silicon and Ti foil for high sensitivity vapor ethanol.The surface topography of the films and the porous silicon was studied by using the Scanning Electron Microscopy (SEM) and the Atomic Force Microscopy (AFM). XRD diffraction showed the appearance of (100) ZnO which has single crystalline with a hexagonal wurtzite while TiO2 has been crystallized in a tetragonal with the preferential orientation of the crystallinity with the prominent (101). The relation between resistance-time show high sensitivity for ZnO,TiO2 and (ZnO:TiO2-x) nanocomposite found to be around (20-80%) at different working temperature.OmniScriptum SRL, Str.
