Paper Abstract

In this contribution we propose an iterative scheme for the solution of the coupled Poisson-Schroedinger system in a self-consistent manner. The developed methodology allows us to analyze the combined effects of piezoelectricity, spontaneous polarization, and the charge density in low-dimensional semiconductor nanostructures. These effects are analyzed here on an example of a wurtzite type semiconductor heterojunction. It is shown that such effects may influence substantially the electronic states and quasi-Fermi level energies of the nanostructures, in particular when compared to one-step calculations based on the conventional schemes. A major emphasis is given to two different types of mechanical boundary conditions.
