Revisiting the effects of Co(2)O(3) on multiscale defect structures and relevant electrical properties in ZnO varistors

Element doping is an effective method to improve the performance of ZnO varistors. Previous studies mainly focused on the variation of microstructures and Schottky barriers. In this study, the effects of Co dopant on electrical properties are investigated from the aspect of multiscale defect structu...
