Abstract
An electric battery comprises a semiconductor junction incorporating an inorganic crystalline compound of Group III and Group V elements of the Periodic Table characterized by a predetermined annealing temperature for defects therein; a nuclear source of relatively high energy radiation and concomitant heat, which radiation causes generation of such defects in the semiconductor junction; and a thermal impedance enclosure for the nuclear source and the semiconductor-junction for retaining therewithin a sufficient quantity of heat to maintain a functional relationship between the generation of defects and the predetermined annealing temperature during operation.
