SiC and GaN Power Devices
Naval Research Laboratory, DC, Electronics Science & Technology Division
The project focuses on developing and characterizing novel SiC and GaN power electronic devices. SiC and GaN power switches have the potential of increasing power converter operation voltage to 10-20kV and increasing the switching frequency by a factor of 10. Current research focuses on characterizing and understanding defects in SiC and GaN materials, the effects that the defects in materials have on SiC and GaN devices performance and reliability, investigation of carrier transport in two-dimensional structures, affect of traps at the semiconductor-dielectric interface on mobility and charge trapping in the dielectric, and device physics or high voltage junction termination region. In addition, novel device structures are being investigated to achieve improved performance, higher operation voltage, and improved reliability.
