Radiation Tolerant High-Voltage, High-Power Diamond Electronics

Great Lakes Crystal Technologies (GLCT), which recently spun out of the world-class diamond materials and devicenbsp;collaboration between Michigan State University (MSU) and MSU-located Fraunhofer USA Center for Coatings and Diamond Technologies (CCD), has a mission to become the leading supplier of high performance diamond for advanced (non-gemstone) applications.Compared to Si, GaAs, 6H- amp; 4H-SiC, and GaN, diamond has the highest electronic figures of merit (FOMs) including Baligarsquo;s DC and high frequency FOMs, Johnsonrsquo;s FOM, and Keyersquo;s FOM. This is because of diamondrsquo;s very high critical field, bandgap, high carrier mobility, and for Keyersquo;s FOM its very high thermal conductivity. Additionally, diamond is the best of these materials in terms of the number and types of defects generated during heavy ion bombardment and its ability to maintain good crystalline structure for high power electronics performance.In the proposed effort GLCT is partnered with MSU and CCDnbsp;who previously under ARPA-E SWITCHES support demonstrated high performance diamond diodes and transistors. This project seeks to extend that work and optimize the devices for high radiation tolerance.
