Abstract :
A fully self-consistent large-signal double-barrier (DB) heterostructure model is reported in this paper. Both dc and ac potentials are self-consistently solved with the Poisson and Schrodinger equations. This ensures that the model provides consistent topologies for both current and charge conservation of each harmonic. With this approach we can really count the impact of ac charge on the harmonic current calculation. Harmonic balance based simulation technique is used to calculated the frequency properties of primary harmonic as well as higher harmonics. A conventional undoped AlGaAs/GaAs/AlGaAs DB structure with thickness of 34 Å/34 Å/34 Å sandwiched between two lightly doped GaAs spacers is used as a test device. Generalized Wannier Picture is used to analyze this DB structure. In this paper, we also develop a new wave function matching technique to estimate the Hamiltonian elements at the interfaces of heterostructure.
