Theoretical study of a GaN-AlGaN high electron mobility transistor including a nonlinear polarization model.

Theoretical study of a GaN-AlGaN high electron mobility transistor including a nonlinear polarization model.

We present a theoretical model of an AlGaN-GaN high electron mobility field effect transistor (HEMT) that includes a nonlinear model of the strain polarization fields produced at the heterointerface. Recent experimental work has indicated that the macroscopic polarization in III-nitride alloys is a...
