The chemical state of grain boundaries in \(\mathrm{Bi}_{2} \mathrm{O}_{3}\)-doped \(\mathrm{ZnO}\) ceramics was investigated by Auger electron spectroseopy. The additive Bi was segregated into grain boundaries 2 to \(3 \mathrm{~nm}\) thick, where oxygen deficiency occurred. Auger transitions \(K L_
## Abstract In this paper a detailed nature of the electrical potential barriers in ZnO based varistors are presented. The excellent nonlinear currentβvoltage (__IβV__) characteristic of these varistors is attributed to the potential barriers formed between the successive ZnO grains during the proc
