Semiconductor nanowires directly grown on graphene – towards wafer scale transferable nanowire arrays with improved electrical contact

Abstract

We present for the first time the growth of dense arrays of silicon and silicon carbide nanowires directly on graphene as well as methods of transferring these novel hybrids to arbitrary substrates. Improved electrical contact for SiC nanowire/graphene hybrid is demonstrated in the application of a robust supercapacitor electrode.
