New microwave detector based on YB2CU3O7-x superconductor structure

Abstract

This paper demonstrantes a potential of asymmetrically-necked superconductor YB2CU3O7-x thin-film device to be used as microwave detector at temperatures above critical temperature Tc of the supercondeuctor. The device patterned by means of photolithography exibits nonlinear and asymmetric current-baised devices in the range of temperatures Tc<T<300 K are explained by means of free carrier nonuniform heating phenomenon.
