Quantitative Icts Measurement of Interface States at Grain Boundaries in ZnO Varistors
, 1997 Isothermal capacitance transient spectroscopy(ICTS) measurement is applied to ZnO:Pr varistors. A simple peak corresponding to the interface states at grain boundaries was obtained and the energy level of the interface states revealed to be monoenergetic

Effect of Ba Addition on Electrical Characteristics of Bi-Based ZnO Varistors
, 2010 With the goal of fabricating low-breakdown-voltage varistors, the effect of adding Ba to ZnO varistors on the ZnO grain size was investigated. Grain growth of ZnO could be markedly promoted by adding both Ba and Bi.
