Different from usual glancing-angle deposition where low surface diffusion is necessary to form nanorods,strongsurface diffusion mediated glancing-angle deposition is exemplified by growing tin nanorod films on both silicon and glass substrates simultaneously via thermal evaporation.During growth,the nanorods were simultaneously baked by the high-temperature evaporator,and therefore re-crystallized into single crystals in consequence of strong surface diffusion.The monocrystalline tin nanorods have a preferred orientation perpendicular to the substrate surface,which is quite different from the usual uniformly oblique nanorods without recrystallization.
