△ [8a-A301-6] Consideration of inter-facet variations of In composition in 3D faceted InGaN quantum wells
Keywords:metal-organic vapor phase epitaxy, selective area epitaxy, polychromatic emission
Three dimensionally (3D) faceted InGaN quantum wells (QWs) are promising for phosphor-free white LEDs. However, the different inter-facet variations of In compositions between the 3D QWs on (0001) and (-1-12-2) is not clearly clarified. In this study, we analyze the dynamics of precursors on the facets, and consider the dominant mechanism to determine the inter-facet variations of In compositions in the 3D QWs on (0001) and (-1-12-2).
