In this work we first report on a theoretical model which provides the gate voltage dependence of the piezoelectric polarization charge in GaN HEMT devices. The model utilizes a generalization of Gauss' law, imposing constraints on the electric displacement vector D. The constraint on D is given ...

The aim of the paper is to present a simple noise model using the Delegedeudeauf formulation for the Fukui constant K F, in order to estimate the minimum noise figure of Gallium nitride (GaN) based MESFET/HEMT devices. The Fukui model is compared with published experimental results of a ...
In GaN HEMTs, the charge trapped at the surface depletes the 2DEG channel and can be quantified by monitoring the dynamic-\(R_{on}\) increase. Therefore, the measurements were done in the linear region since, for a given voltage, current is inversely proportional to the dynamic-\(R_{on...
