【 摘 要 】
When tin oxide is doped with Sb2O3 and CoO, it shows highly nonlinear current (ð¼)â€�?�voltage (ð‘�??) characteristics. Addition of CoO leads to creation of oxygen vacancies and helps in sintering of SnO2. Antimony oxide acts as a donor and increases the conductivity. The results are nearly the same when antimony oxide is replaced by tantalum oxide. The observed nonlinear coefficient, ð›�? = 30 and the breakdown voltage is 120 V/mm.
