Varistor piezotronics: Mechanically tuned conductivity in varistors
Journal of Applied Physics, 2015The piezoelectric effect of ZnO has been investigated recently with the goal to modify metal/semiconductor Schottky-barriers and p-n-junctions by application of mechanical stress. This research area called “piezotronics” is so far focused on nano structured ZnO wires.

Degradation phenomena of ZnO varistors
Physica Status Solidi (a), 1981The 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.

Microchemistry of ZnO Varistors
Proceedings, annual meeting, Electron Microscopy Society of America, 1992ZnO 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 ...

IEEE Electrical Insulation Magazine, 1989
An overview is given of zinc oxide varistors, which are made of semiconducting ceramics with highly nonohmic current-voltage characteristics, which originate at the grain boundaries. These varistors are widely utilized to protect electric power lines and electronic components against dangerous voltage surges.

Journal of the American Ceramic Society, 1999
The development of varistor ceramics is reviewed with an emphasis on ZnO‐based varistors formed by liquid‐phase sintering. Particular attention is given to the effects of microstructural disorder on the properties of varistors and to the different modes of failure that can occur.
