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.

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.

Impulse current withstanding capability of ZnO varistors with influence of varistor size
IEEJ Transactions on Electrical and Electronic Engineering, 2019Through injecting 8/20 and 30/60 μs impulse currents to five kinds of ZnO varistors, the influence of the varistor size on the single impulse current withstanding capability of a ZnO varistor is investigated in this article. A comprehensive damage criterion of a varistor consisting of three aspects, namely, mechanical failure by visual inspection ...

A composite varistor material containing silicon carbide, a conductor, and an insulator has been developed. The material has rubberlike flexibility and is easily formed. A higher leakage resistivity (∼1012 Ω cm) and greater nonlinearity (∼10) than for silicon carbide varistors permit the material to be used as a gapless surge suppressor.

Two shapes of interdigitated planar varistors were made using thick-film technology on alumina substrates. These varistor were based on ZnO paste. The distance between varistor electrodes were changed from 0.2 to 1.91 mm, and the total length of the electrodes from 49 to 230 mm.
