Abstract
An improved contact material for use in the fabrication of semiconductor devices is provided. This material comprises one of the mercury chalcogenides. The application of this material to a nondegenerate semiconductor may be made by the process of evaporation. The resulting contact is stable in the atmosphere, and is more electronegative than the best contact material, namely gold, that is now used.
