Superconductivity in fcc Mo(x)Nb(1-x)/N(y)C(1-y)/z thin films
Abstract
An attempt is made to prepare the hypothesized high conductivity material Mo(x)Nb(1-x)/N(y)C(1-y)/z in thin films, where x = 0-0.93, y = 0.8-1.0, and z = 0.5-1.0. The films have been produced in a UHV system by reactive RF sputtering of a split Mo-Nb target in mixtures of Ar, N and cyanogen gases. Critical temperature is found to initially decrease with increasing Mo content, reaches a minimum, and then begins to increase on the Mo-rich composition side, where N deficiencies in the structure are significant. N implantation increases lattice properties of Nb-rich samples.
