Abstract
Single gram-boundary varistors were fabricated using hydrothermal and vapor phase grown ZnO single crystals and their voltage-current relation was studied. The single crystal bonded single junction varistor showed various voltage-current relationship and different breakdown voltage of 0.24-3V. The different types of non-linear current voltage behaviors was attributed to the variation of electrical conductivity in ZnO single crystals.
