Self-consistent calculation of Schrodinger-Poisson equation including parallel-perpendicular kinetic energy coupling effects in semiconductor quantum wells

摘要

At heterostructure boundaries under effective mass approximation, the parallel momentum conservation results in the coupling between the perpendicular and parallel kinetic energies. We present the first results of fully self-consistent calculation including these kinetic energy coupling effects using a newly developed self-consistent Schrodinger-Poisson equation solver. As an application, we apply this solver to the calculation of intersubb and optical absorption coefficients in QW structures.
