Abstract: Controlling shape and orientation is important for the synthesis of functional nanomaterials. In this work, nanoscale Cu3Si triangles, squares, and wires have been grown on Si(111), (100), and (110) substrates, respectively, through a template-free Au-nanoparticle-assisted vapor transport method. The sides of nanotriangles and nanosquares and the growth direction of the nanowires are all along Si 110, giving rise to long-range ordering of the nanostructures. Au nanoparticles absorb Cu vapor and facilitate the rate-limited diffusion of Si, which is critical for the shape-controlled growth of Cu3Si. This bottom-up approach to synthesize shape- and orientation-controlled Cu3Si nanostructures might be applicable to the tailored growth of other materials.
