Abstract
The invention provides a self-powered device having at least one substrate, at least one radioactive power source formed over the substrate, and integrated circuits formed over the substrate. The radioactive power source includes a first active layer of a first conductivity type, a second active layer of a second conductivity type. The first and second active layers form a depletion layer. A tritium containing layer is provided which supplies beta particles that penetrates the depletion layer generating electron-hole pairs. The electron-hole pairs are swept by the electric field in the depletion layer producing an electric current.
