Nonlinear electronic transport in weakly coupled superlattices results in formation of electric field domains, self-sustained current oscillations (periodic, quasiperiodic or chaotic), wave propagation and other interesting phenomena. These are explained here by means of a discrete self-consistent model including quantum mechanically calculated tunneling current, detailed electrostatics and appropiate boundary conditions. Simpler discrete drift-diffusion models (for which analytical results are known) are also derived from our model.
