The devices are studied by means of an ensemble Monte Carlo simulation that includes all relevant scattering mechanisms. The energy levels and wave functions are determined by a self-consistent resolution of the Schrödinger and Poisson equations. The influence of the modelling of carrier-carrier scattering is discussed on the example of a resonant-phonon structure operating at 3.4 THz. To demonstrate the usefulness of such a model for optimization purpose, an alternative design operating at a lower frequency is proposed. Our model predicts that a significant population inversion can be achieved at about 1 THz.Lire moins >
