Novel applications of Tl-Ca-Ba-Cu-O thin films to active and passive high frequency devices
Abstract
Applications of high temperature superconducting thin films to the development of new passive and active circuitry operating up to 40 GHz are presented. Thin film deposition (including new results on the effect of low temperature anneals), patterning Tl-based films to linewidths of 3 microns, and contacting are discussed. A number of high-temperature superconducting devices are discussed including passive resonators, passive filters, and an active device. The active device is the superconducting flux flow transistor (SFFT), that can be used in applications such as amplifiers and phase shifters.
