| Abstract: | SnO2 Nano-Particle films were deposited by DC gas discharge activating reac-tive evaporation. The morphology, struture, composition and properties of SnO2 filmswere studied by SEM, XRD, AES. Using the apparatus made by ourselves, the rela-tionship between films resistance and time was studied when SnO2 nano-particle filmswere in electric field strength about 105 V/m. Futhermore, the electrical properties andthe gas sensitive characteristics for C2H5OH were investigated when SnO2 nano-particlefilms were in the electric field. The preciple of gas-sensitive of SnO2 nao particle filmshave been explained. |
