Popis: Results of Monte Carlo simulation of mid-infrared QCL structure initially proposed by Page et al. [Appl. Phys. Lett. 78, 3529 (2001)] are presented. The band-bending effect imposed by non-equilibrium electric charge distribution during the laser operation is observed. Perturbations of electric potential, non-equilibrium charge and electron sub-bands populations are demonstrated for a realistic range of electron sheet densities levels. Full Text: PDF References: C.
