Popis: We present a microscopic analysis of electronic noise in short channel δ-doped AlInAs/GaInAs HEMTs. A classical Monte Carlo device simulation, appropriately modified to locally introduce the effects of electron degeneracy and nonequilibrium screening, is used for the calculations. Even if the energy quantization in the channel is not taken into account in the Monte Carlo model, its validity has been checked by means of the comparison with experimental results of static characteristics, small signal behavior and noise performance in a recessed 0.1 μm T-gate δ-doped HEMT (InP based). The geometry and layer structure of the simulated HEMT is completely realistic, including recessed gate and δ-doping configuration and also the T-shape of the gate and the dielectric disposition has been included in the simulation
