Abstract
A voltage-dependent resistor of the layered structure type is provided by employing the nonohmic property of the hetero-junction between a zinc oxide layer and a metal oxide layer consisting essentially of at least one member selected from the group consisting of cobalt oxide, manganese oxide, barium oxide, strontium oxide, lead oxide and rare earth oxides.
Claims7
A voltage-dependent resistor of layered structure type, comprising a zinc oxide layer adjacent to a metal oxide layer consisting of at least one member selected from the group consisting of cobalt oxide (Co.sub.2 O.sub.3), manganese oxide (MnO.sub.2), barium oxide (BaO), strontium oxide (SrO), lead oxide (PbO) and rare earth oxides with electrodes applied to opposite surfaces of said zinc oxide layer and said metal oxide layer.
