Abstract
Quantum-well doped p-channel AlGaAs/GaAs0.85Sb0.15 /GaAs heterostructure field-effect transistors (HFETs) with 50-μm gate lengths and 400-μm gate widths are reported. Using a simple analytical model, accurate values of the low-field hole mobility, the threshold voltage, parameters characterizing the gate leakage current, and the saturation currents and voltages are obtained. The calculation results are shown to be in good agreement with the experimental data
