Abstract

The variations of the energy levels in a conduction quantum well of InP/InAs/InP versus its width are calculated using two different approaches: a self-consistent tight-binding calculation and an effective-mass description. The introduction of nonparabolicity appears to have a noticeable effect. The importance of taking into account the nonparabolicity becomes essential in the estimation of the equivalent parallel effective mass, which characterizes the parallel transport in such systems.
