Abstract

The empirical pseudopotential method has been used to conduct band structure calculations on gallium and indium nitride and their alloys. Initially, the pseudopotential form factors required for the semi-empirical calculations were obtained using a Monte Carlo fitting approach to obtain good agreement of the predicted band structure with experimental and first-principles band structure results for bulk, unstrained GaN and InN. Empirical band structures were then found using a model based on the virtual crystal approximation for a series of compositions of the alloy GaInN. A complete set of K · p parameters have been extracted from our empirical models using a method which obtains the parameters directly from k · p formulae for them in terms of the wavefunctions and energies at the zone centre.
