    摘要: The invention discloses a semiconductor light-emitting device and a method of fabricating the same. The semiconductor light-emitting device according to the invention includes a substrate, a buffer layer, a multi-layer structure, and an ohmic electrode structure. The buffer layer is selectively formed on an upper surface of the substrate such that the upper surface of the substrate is partially exposed. The multi-layer structure is formed to overlay the buffer layer and the exposed upper surface of the substrate. The multi-layer structure includes a light-emitting region. The buffer layer assists a bottom-most layer of the multi-layer structure in lateral and vertical epitaxial growth. The ohmic electrode structure is formed on the multi-layer structure.

    摘要: A thick gallium nitride (GaN) film is formed on a LiAlO2 substrate through two stages. First, GaN nanorods are formed on the LiAlO2 substrate through chemical vapor deposition (CVD). Then the thick GaN film is formed through hydride vapor phase epitaxy (HVPE) by using the GaN nanorods as nucleus sites. In this way, a quantum confined stark effect (QCSE) becomes small and a problem of spreading lithium element into gaps in GaN on using the LiAlO2 substrate is mended.
