Abstract :
The role of average composition and local compositional fluctuations on the structural properties of Ga1-yInyAs1-xNx quaternary alloys and related ternary alloys was investigated by means of accurate density functional pseudopotential calculations. For the quaternary alloy, the authors focus particularly on the case with x=0.5 and y=0.5. They study the different anion-cation bond length distributions and the macroscopic average structural parameters.
