Abstract

Structural and optical properties of coherent GaN islands grown on 6H-SiC(0001) surfaces via the vapor-liquid-vapor (VLS) mechanism were investigated. The microstructure of GaN islands was studied by high-resolution cross-sectional transmission electron microscopy, morphology by atomic force microscopy, and assembly of islands by scanning electron microscopy. Micro-Raman spectroscopy results showed the existence of tensile strain in the GaN islands.
