Abstract
The stoichiometry and free-carrier concentration of mercury cadmium telluride is adjusted by a heat treatment. Mercury cadmium telluride is slowly cooled from a temperature near the solidus temperature to room temperature in the presence of constituent vapor. The mercury cadmium telluride is maintained at the lowest temperature within the capsule during cooling.
