Growth of GaN nanostructures on graphene

GaN nanostruetures with different morphologies are grown on few layer graphene (FLG) as template, using chemical- vapor-deposition technique in a self catalytic process using the large surface energy of graphene. Raman and photoluminescence studies reveal wurtzite GaN phase. Morphologies of these nanostructures varied depending on the number of layers in each template. Photoluminescence study reveals that growth occurs without deterioration of FLG layers and no incorporation of carbon in GaN nanostructures.
