Abstract
We assess the impact of nonlinear electronic transport and, in particular, of real space transfer (RST) on device performance for advanced III/V high electron mobility transistors (HEMTs) using the device simulator MINIMOS-NT. In this context, we discuss dc and RF performance issues for pseudomorphic AlGaAs/InGaAs/GaAs HEMTs that are especially relevant for gate-lengths of about 150 nm. All results are compared to and found to be consistent with experimental data for devices processed in tow different foundries.
