Is there a compact model for GaN HEMTs?
In this thesis, a physics-based compact model is developed for short channel GaN HEMTs. The model is based on the concept of virtual source (VS) transport origi- nally developed for scaled silicon \feld e\u000bect transistors. Self-consistent current and charge expressions in the model require very few parameters.

Why are GaN based high electron mobility transistors important?
Gallium Nitride (GaN)-based high electron mobility transistors (HEMTs) are rapidly emerging as front-runners in high-power mm-wave circuit applications. For circuit design with current devices and to allow sensible future performance projections from device engineering in such a rapidly evolving technology, compact device models are essential.
