Post Silicon, Gallium Nitride (GaN) has emerged as the WONDER material that has the potential to disruptively change the future of semiconductor devices. Bolstered by its unique material and device properties, it is finding extensive applications both in power and RF domains; e.g. 5G, power switches, etc. This technology is expanding to capture the market of electric vehicles, besides being pushed towards applications in extreme environments (automobiles, low earth orbit satellites, high temperature and radiation hard applications) and even for quantum computing. At CNNP, GRAND group works towards development of indigenous GaN technologies and systems through detailed physical analysis, to meet the nation's needs for a sustainable and prosperous future.
