英文摘要	Two-dimensional zno nanowall networks were grown on zno-coated silicon by thermal evaporation at low temperature without catalysts or additives. all of the results from scanning electronic spectroscope, x-ray diffraction and raman scattering confirmed that the zno nanowalls were vertically aligned and c-axis oriented. the room-temperature photoluminescence spectra showed a dominated uv peak at 378 nm, and a much suppressed orange emission centered at similar to 590 nm. this demonstrates fairly good crystal quality and optical properties of the product. a possible three-step, zinc vapor-controlled process was proposed to explain the growth of well-aligned zno nanowall networks. the pre-coated zno template layer plays a key role during the synthesis process, which guides the growth direction of the synthesized products.
