Title: The Innovations of William E. Spicer
Introduction
William E. Spicer is a notable inventor based in Stanford, California, recognized for his contributions to the field of semiconductor technology. He holds a total of six patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on the development of advanced materials and devices that enhance the performance of III-V semiconductors.
Latest Patents
Among his latest patents is a groundbreaking method for the passivation and insulation of III-V devices using pnictides. This includes the creation of pnictide thin films, particularly phosphorus, which are grown on III-V semiconductors such as InP, GaP, and GaAs. These films exhibit a unique layer-like, puckered sheet-like local order and are typically 400 Angstroms thick. They are preferably grown by molecular beam deposition, although other methods like vacuum evaporation, sputtering, and chemical vapor deposition can also be employed. The pnictide layers significantly reduce the density of surface states, allowing for modulation of the depletion layer and improvements in electron concentration at the surface. This innovation leads to decreased surface recombination velocity and increased photoluminescence intensity. These layers have applications in various devices, including MISFETs, MESFETs, and opto-electronic devices such as light-emitting diodes and solar cells.
Another significant patent involves an improved transferred electron III-V semiconductor photocathode. This design features an aluminum contact pad and grid structure that enhances quantum efficiency by facilitating electron escape into the vacuum and controlling dark spot blooming from bright photon emission sources.
