摘要: A scattering matrix formalism is developed for the transport of electrons in heterostructures. It shown how approach may be used to calculate properties superlattices and non-periodic devices. The applied, within an empirical pseudopotential model, calculation tunnel junction fluxes through a GaAs/AlAs double barrier structure. When comparison analysis conventional one-band effective-mass model made, significant deviations between two approaches are found result.
