An analytical thermal model of AlGaN/GaN high electron mobility transistor (HEMTs) has been developed. This temperature dependent model incorporates the polarization effects at heterointerface. The model also accounts for the mobility degradation with increase in temperature, which is one of the major causes in deteriorating the driving current. By using the variation of band gap with temperature,...
In recent years, double gate high electron mobility transistor (DGHEMT) have been introduced to provide better immunity to short channel effects which are inescapable with downscaling of the single gate devices due to fundamental limit on gate-to-channel thickness. Furthermore, in sub 100 nm regime, for lower device aspect ratio, channel thickness also becomes an important parameter affecting the...
An accurate non linear charge-control model of the two dimensional electron gas (2-DEG) of an insulated gate AlGaN/GaN HFET is proposed which incorporates the dominant effect of polarization induced charge at the AlGaN/GaN interface. It is based on new polynomial dependence of sheet carrier density on position of quasi Fermi level to consider the quantum effects and to validate it from sub threshold...
