A simple theoretical model was formulated which confirmed and explained experimental observations. The phenomenological model takes into account the variation of confinement factor, and it has been validated by measurements. Results from this model demonstrate the importance of carrier distribution dynamics in establishing stable operation and prediction of turn-on and turn-off regimes.","PeriodicalId":114744,"journal":{"name":"1999 Symposium on High Performance Electron Devices for Microwave and Optoelectronic Applications.
