A method for energy-assisted atomic layer deposition and removal of a dielectric film are provided. In one embodiment a substrate is placed into a reaction chamber and a gaseous precursor is introduced into the reaction chamber. Energy is provide by a pulse of electromagnetic radiation which forms radical species of the gaseous precursor. The radical species react with the surface of the substrate to form a radical terminated surface on the substrate. The reaction chamber is purged and a second gaseous precursor is introduced. A second electromagnetic radiation pulse is initiated and forms second radical species. The second radical species of the second gas react with the surface to form a film on the substrate. Alternately, the gaseous species can be chosen to produce radicals that result in the removal of material from the surface of the substrate.

The present invention is a power cell for directly converting ionizing radiation into electrical energy. The invented isotopic electric converter provides an electrical power source that includes an electronegative material layered in a semiconductor, to form a first region that has a high density of conduction electrons, and an electropositive material also layered in the semiconductor material to form a second region with a high density of holes. Said N-layers region and P-layers region are separated by a neutral zone of semiconductor material doped with a radioactive isotope, such as, but not limited to, tritium. No junction is formed between the N and P layers regions. Rather, the potential gradient across the neutral zone is provided by the difference between the work functions of the electronegative and electropositive electrodes. Electrical contacts are affixed to the respective regions of the first and second type conductivity which become the anode and cathode of the cell, respectively. Beta particles emitted by the tritium generate electron-hole pairs within the neutral zone, which are swept away by the potential gradient between the first and second regions, thereby producing an electric current.
