Laser fabrication of electrodes on zinc oxide varistors

Abstract
Near surface properties are reported for ZnO varistors irradiated with high-intensity pulses from both KrF excimer and CO2 lasers. Electrical, optical, and Rutherford backscattering measurements reveal that a thin conducting film is formed by pulsed-laser heating of a varistor surface. The conductive film is evaluated as a varistor electrode.
