Technology Description:

The University of Illinois at Urbana-Champaign is developing diamond semiconductor switching devices to enable revolutionary breakthroughs in electricity grid protection. The proposed device is composed of light-triggered ultrawide-bandgap materials and overcomes the voltage and current limitations of conventional photoconductive devices. If successful, the device will be a critical component in higher-temperature, more efficient, and reliable power electronics.
