Our research focuses on the development of oxide materials and the incorporation of these oxide materials in high performance transistor applications. Current investigations include beta-Ga2O3 MOSFETs, ZnO and InGaZO thin film transistors, and impurity doped ZnO thin films for transparent conductors.
The research entails device design, fabrication, and testing, as well as optimization and analysis of material microstructural and morphological properties to achieve enhanced device performance with particular emphasis on ALD gate dielectric, ohmic contact, and associated interface development. Research is conducted in a fully equipped ISO-5 device fabrication clean room. Materials characterization capabilities include electron microscopy, ellipsometry, x-ray diffraction, atomic force microscopy, Hall effect and photoluminescence.
