Latest Patents: One of Joseph Bonaventura's latest inventions is a patent for GaN-based nitric oxide sensors and methods of making and using the same. This advanced technology involves GaN-based heterojunction field effect transistor (HFET) sensors equipped with engineered, functional surfaces that serve as pseudo-gates, modifying the drain current upon analyte capture. In several embodiments, the device is designed to sense nitric oxide (NO) species in a NO-containing fluid. The composition of the semiconductor structure includes a pair of separated GaN layers and an AlGaN layer interposed between and in contact with the GaN layers. Source and drain contact regions are formed on one of the GaN layers, while an exposed GaN gate region is situated between these contact regions, allowing interaction with the NO-containing fluid. This semiconductor structure is optimally fabricated on substrates such as SiC, with an insulating layer covering the structure, featuring a window that maintains exposure of the GaN gate region for contact with the NO-containing fluid. The innovation also contemplates incorporating a metalloporphyrin adsorbed on the GaN gate region to enhance NO detection capabilities.
