A composition of matter comprising: a plurality of group III-V nanowires or nanopyramids epitaxially grown on a polycrystalline or single-crystalline graphene layer, said graphene layer being directly supported on a crystalline substrate such as a group III-V semiconductor, sapphire, SiC or diamond substrate, wherein the epitaxy, crystal orientation and facet orientations of said nanowires or nanopyramids are directed by the crystalline substrate.

Composition of matter

A process for growing nanowires or nanopyramids comprising: (I) providing a graphitic substrate and depositing AlGaN, InGaN, AlN or AlGa(In)N on said graphitic substrate at an elevated temperature to form a buffer layer or nanoscale nucleation islands of said compounds; (II) growing a plurality of semiconducting group III-V nanowires or nanopyramids, preferably III-nitride nanowires or nanopyramids, on the said buffer layer or nucleation islands on the graphitic substrate, preferably via MOVPE or MBE.
