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.

DC Overload Behavior of Low-Voltage Varistor-Based Surge Protective Devices
IEEE Transactions on Power Delivery, 2020This letter provides evidence of a peculiar behavior of metal-oxide varistors under DC overvoltages. It stresses the need for extending the V–I characteristic of varistors in the time domain so as to accurately predict the dynamic performance of varistor-

Journal of Applied Physics, 1988
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.

[1991 Proceedings] 6th Mediterranean Electrotechnical Conference, 2002
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.

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.
