Abstract
A multi-color, solid-state lighting device includes a stack of two or more panels, each panel having an array of light emitting semiconductor components formed thereon. To form the light emitting components, high quality epitaxial layers of monocrystalline materials can be grown overlying a monocrystalline layer of silicon formed on a low cost substrate, such as glass. The growth of the monocrystalline materials is accomplished by forming a compliant substrate for growing the monocrystalline materials. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a silicon by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer.
