Abrupt metal-insulator transition element, high-voltage noise removal circuit using the abrupt metal-insulator transition element, and electric / electronic system including the circuit

摘要

An abrupt MIT device, a high-voltage noise removing circuit using the same, and an electrical and electronic system with the circuit are provided to remove a high-voltage noise higher than a limit voltage of each of the abrupt MIT devices by using serially-connected abrupt MIT devices. An abrupt MIT(Metal-Insulator Transition) device includes a substrate(100) and first and second abrupt MIT structures(600,600a) respectively formed on an upper surface and a lower surface of the substrate. Each of the first and second abrupt MIT structures has a characteristic of an insulator below a predetermined limit voltage and has a characteristic of a metal above the limit voltage. Each of the first and second abrupt metal-insulator transition structures has an abrupt MIT thin film and at least two electrode thin films contacting the abrupt MIT thin film.
