It is demonstrated that atomic species differing in covalent tetrahedral radii are not randomly distributed in mixed III–V and III–N layers. They self-assemble into phase separated and ordered regions.
The salient features of phase separation in InGaAsP and InGaN layers are presented and discussed. The occurrence of atomic ordering in InGaAsP, InGaAs, and InGaN layers is considered. The mechanisms of the formation of double and triple period super-lattices in arsenides and phosphides are presented. The influence of these microstructural features on the degradation resistance of III–V emitters is discussed.
