Development of Curie point switching for thin film, random access, memory device

Managanese bismuthide films are used in the development of a random access memory device of high packing density and nondestructive readout capability. Memory entry is by Curie point switching using a laser beam. Readout is accomplished by microoptical or micromagnetic scanning

Photoelectrolysis Of Water By Solar Energy

The direct conversion of solar energy to chemical fuel is possible by photodecomposition of water on semiconducting electrodes. We have observed 100% quantum efficiency for this reaction without corrosion of the electrodes. Projected costs of large area, thin film devices, utilizing existing technology, indicate that the hydrogen fuel can be cost competitive with other fuels now
