Abstract
The effect of crystallization of ZnO on volt-ampere characteristics was investigated. It was shown that incorporation of Bi2O3, TiO2, and SnO2 causes crystal growth, while Sb2O5, CoO, and MnO slow crystal growth. The formation of a finely crystalline structure with thin layers of glass phase increases the volt-ampere characteristics.
