Abstract :
We present a multiband envelope-function model for wurtzite nanostructures based on a rigorous numerical procedure to determine operator ordering and band parameters from nonlocal empirical pseudopotential calculations. The proposed approach leads to numerically stable envelope equations that accurately reproduce full-Brillouin-zone subband dispersions of quantum systems obtained within the linear combination of bulk bands.
