Notes:
The electrical transport properties of zinc oxide varistors are correlated with the chemistry of their grain boundaries. An adsorbed layer of bismuth, about 5 A(ring) thick, is necessary to create potential barriers at the grain boundaries. The height of these potential barriers depends sensitively on the excess amount of oxygen (∼1 monolayer) present at the interfaces between grains. This oxygen enrichment is influenced by thermal processing and by electrical degradation.
