Abstract
A radioisotope-powered semiconductor battery comprises a substrate of a crystalline semiconductor material, the material having at least one degree of confinement, and a radioactive power source comprising at least one radioactive element. The power source is positioned relative to the substrate to allow for impingement of emitted particles on the substrate. The semiconductor material may be electronically, structurally or chemically confined. The radioactive element is preferably impregnated within or immediately adjacent the semiconductor material.
