Introduction
Gerald B Stringfellow is a notable inventor based in Salt Lake City, UT (US). He has made significant contributions to the field of semiconductor technology, holding 2 patents that reflect his innovative approach to material science.
Latest Patents
One of his latest patents is titled "Use of surfactants to control island size and density." This patent describes methods for controlling island size and density on an OMVPE growth film by adding a surfactant at a critical concentration level. The process allows for a growth phase for a specified period, concluding when the desired island size and density are achieved. For instance, the island size and density of an OMVPE grown InGaN thin film can be regulated by incorporating an antimony surfactant at a critical concentration level.
Another significant patent is "Methods for enhancing P-type doping in III-V semiconductor films." This invention provides methods for doping a semiconductor film by epitaxially growing the III-V semiconductor film in the presence of a dopant, a surfactant that acts as an electron reservoir, and hydrogen. The conditions are optimized to promote the formation of a III-V semiconductor film doped with the p-type dopant. In some embodiments, the epitaxial growth of the doped III-V semiconductor film begins at a first hydrogen partial pressure, which is then increased during the growth process.
