Os mecanismos de crescimento de poços quânticos InGaN facetados tridimensionalmente (3D) (QWs) em (= 1 = 12 = 2) substratos GaN são discutidos. A estrutura é composta pelos planos (=1=12=2), {=110=1} e {=1100}, e o formato da seção transversal é semelhante ao dos QWs 3D em (0001). No entanto, os QWs 3D em (=1=12=2) e (0001) mostram variações de interface bastante diferentes das composições In. Para esclarecer esta observação, as espessuras locais dos constituintes InN e GaN no GaN 3D são ajustadas com uma fórmula derivada da equação de difusão. Sugere-se que a diferença na eficiência de incorporação de cada plano cristalográfico afeta fortemente a superfície na migração do adatom.

Abstract: The growth mechanisms of three-dimensionally (3D) faceted InGaN quantum wells (QWs) on (=1=12=2) GaN substrates are discussed. The structure is composed of (=1=12=2), {=110=1}, and {=1100} planes, and the cross sectional shape is similar to that of 3D QWs on (0001). However, the 3D QWs on (=1=12=2) and (0001) show quite different inter-facet variation of In compositions. To clarify this observation, the local thicknesses of constituent InN and GaN on the 3D GaN are fitted with a formula derived from the diffusion equation. It is suggested that the difference in the In incorporation efficiency of each crystallographic plane strongly affects the surface In adatom migration.
