Abstract
The electrical conductivities and transition temperatures of films consisting of random mixtures of Hg and Xe condensed onto substrates held at 4.2 K have been measured. A metal-nonmetal transition in which the temperature coefficient of resistance changes from positive to negative has been found near a volume fraction close to that expected for random percolation. This transition is accompanied by a substantial drop in the superconducting transition temperature which is measured resistively.
