Abstract: A semiconductor switch, using transition metal oxides, is provided that can be made to undergo a very sudden metal-tosemiconductor transition as a function of an electric field instead of as a function of temperature. Certain transition metal oxides act like semiconductors having valence and conduction bands. When enough mobile charge carriers move into the conduction band, the gap between the conduction and valence band disappears and the metal oxide acts like a metal. The metal oxide, which is being held at a temperature very close to its transition threshold, is employed with an insulated electrode (serving as a gate) capable of supplying mobile carriers to the metal oxide. When a proper bias is applied to the gate electrode, the metal oxide is switched into its high-conduction (metal) state, allowing the flow of current therethrough.
