Technology Description:

Great Lakes Crystal Technologies is developing a diamond semiconductor transistor to support the control infrastructure needed for an energy grid with more distributed generation sources and more variable loads. The proposed transistor takes advantage of the properties of diamond, an ultrawide-bandgap semiconductor material with better thermal management, lower power loss, and higher operating voltage than conventional materials. The device switches can be controlled by light source and electrical means, improving electromagnetic interference immunity.
