Abstract (en)
A metal oxide varistor with controllable breakdown voltage and capacitance characteristics is fabricated by controlled diffusion of lithium into conventional metal oxide varistor material at elevated temperature. The varistor layer containing lithium exhibits an increased breakdown voltage, lowered capacitance, and low leakage current while maintaining a high coefficient of nonlinearity.
