Abstract :
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 calculations 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 intersubband optical absorption coefficients in QW structures.
