Abstract: This chapter is designed to study phase separation and order in cubic ternary and quaternary nitride alloys. It reviews the recent developments achieved in the study of group-III nitride alloys, focusing on the thermodynamic properties of the ternaries AlGaN, InGaN, InAlN, BGaN, BAlN, as well as the quaternary AlGaInN alloys in their cubic (zinc blende) phase. The properties of the alloys have been studied by means of ab initio total energy and electronic structure calculations, combined with cluster expansion (CE) methods, for the treatment of disorder and composition effects, either within a generalized quasi-chemical approach (GQCA) or using the Monte Carlo (MC) simulations. This chapter discusses the results of the calculations for InGaN with focus on the origin of the light emission process in the InGaN-based optoelectronic devices through a comparison with recent high resolution X-ray and Raman spectroscopy measurements. © 2005 Elsevier B.V.
