| Popis: | Thin films of ZnO:SnO2 were deposited on different substrates like glass and c-Si using spray pyrolysis method .The structures and morphology of the prepared samples films were cheeked using X-ray diffraction and atomic force microscope. Gas sensing measurements provided from resistance measurement in the absent and exposure to NO2 gas . The results showed that good enhancement of sensitivity take place after doping with tin oxide. Maximum sensitivity obtained at 9% doping ratio and operating temperature 200oC. Comment: 13pages, 9 figures |
