Abstract
Abstract Mercury cadmium telluride is disclosed having a quantity of a halogen donor material preferably selected from the group consisting of bromine and iodine dispersed therein in an amount sufficient to measurably increase the donor concentration. Also disclosed are PN junctions formed using this donor material. A method of introducing the donor material is additionally disclosed.
