Electrophoretic Formation of Zinc Oxide Based Ntc Rsistors (RESEARCH NOTE) |
|
| چکیده انگلیسی مقاله |
Fine zinc oxide particles were electrophoretically deposited on alumino-ferro-chrome substrates. The deposition was carried out in a cylindrical ZnO/acetone electrophoresis cell. The deposits were dried and sintered at 1030³C in air. The process resulted a porous polycrystalline ZnO cladding over the alloy core. Comb shaped silver electrodes were formed and fired at 350³C. The variation of device resistance vs. temperature was studied in air in the range of 100 - 250³C. The NTC of resistivity at 100³C and the activation energy of carrier generation was found to be 4.0% K-1 and 1.1eV respectively. |
