Abstract :
The heterostructure potential of a tri-gate depleted mode p-HEMT was modeled for conventional and tailored field operation conditions. The set of energy levels in quantum wells under same bias on all gates were compared with parameters of p-HEMT, when the bias on the gates are varied. To make electron flow in p-HEMT with more coherent energy is documented by modeling and confirmed by experimental measurements of I-V curves and gain.
