AB We introduce a model of a nonlinear double-barrier structure to describe in a simple way the effects of electron-electronscattering while remaining analytically tractable. The model is based on a generalized effective-mass equation where anon linear local field interaction is introduced to account for those inelastic scattering phenomena. Resonance peaks seenin the transmission coefficient spectra for the linear case appear shifted to higher energies depending on the magnitude ofthe non linear coupling. Our results are in good agreement with self-consistent solutions of the Schrodinger and Poissonequations. The calculation procedure is seen to be very fast, which makes our technique a good candidate for a rapidapproximate analysis of these structures.
