Abstract
A voltaic cell uses a radioactive material for energy. Energetic particles emitted by the radioactive material boost charge carriers within a semiconductor lattice into higher energy bands. Dielectric layers having quantum dots tuned by size and spacing (density) to favor particles having specific energies permit quantum mechanical tunneling of the charge carriers before they lose significant energy, are captured, or recombine. The energetic carriers tunnel to an electrical circuit, where they perform work.
