Photoluminescence study of ZnO varistor stability

Journal of Electronic Materials, 1995
Photoluminescence (PL) measurements were carried out on commercial ZnO varistor samples that were electrically stressed and/or annealed at different temperatures. Changes in the intensity of green and yellow luminescence centers were studied as a function of annealing treatment.

Degradation phenomena of ZnO varistors

Physica Status Solidi (a), 1981
The dc degradation behaviour of ZnO varistors as a function of the variables current, temperature, and time is investigated. The degradation rate is phenomenologically presented by an equation reflecting the observed aging behaviour in dependence on the influencing variables.

Origin of ZnO Varistor

Journal of the American Ceramic Society, 1987
The varistor properties were examined in porous ZnO. The sample used contained no dopants such as Bi 2 O 3 or Pr 6 O 11 , which are usually considered to be useful in ...

Microchemistry of ZnO Varistors

Proceedings, annual meeting, Electron Microscopy Society of America, 1992
ZnO varistors are made by mixing semiconducting ZnO powder with powders of other metal oxides e.g. Bi2O3, Sb2O3, CoO, MnO2, NiO, Cr2O3, SiO2 etc., followed by conventional pressing and sintering. The non-linear I-V characteristics of ZnO varistors result from the unique properties that the grain boundaries acquire as a result of dopant distribution ...
