Abstract :
A novel device model has been established for GaN HEMT, featuring polarization induced, positive/ negative charge pairs. Unconventional techniques are found necessary to characterize, and to optimize the design of the polar semiconductor based device for transient (current collapse) free, efficient, microwave power amplification in communication systems.
