Development of a Versatile Physics-Based Finite-Element Model of an AlGaN/GaN HEMT Capable of Accommodating Process and Epitaxy Variations and Calibrated Using Multiple DC Parameters (Postprint)
Abstract
We present a physics-based finite-element model of operation of an AlGaN/GaN HEMT with device geometry inputs taken from transmission electron microscope cross sections and calibrated by comparison with measured electrical data comprising standard field-effect transistor metrics and less well-known model parameters. A variety of electrical outputs from the model are compared to experiment, and the level of agreement is reported.
