초록

In this study, an analytical model for I-V characteristics of an n-AIGaAs / GaAs Delta doped HEMT is proposed. The two-dimensional electron gas density and the conduction band edge profile are calculated from a self-consistent iterative solution of the Poisson equation. The parameters, which include the saturation velocity, two-dimensional electron gas concentration, thickness of the doped and undoped layer(AIGaAs, GaAs, spacer etc.,), are in good agreement with the independent calculations.
