Paper Abstract

In this paper the properties of excitons and phonons in doped GaN is reviewed. We demonstrate that in heavy Ge doped GaN new quasi particle can be stabilized. Furthermore, we discuss and use the observation of local phonon modes to clarify the incorporation of germanium, silicon, carbon, and transition metal ions on different lattice places in the nitride material.
