摘要

One-dimensional tilted carbon nanorod arrays were synthesized on molybdenum substrates by using the catalyst-assisted oblique angle deposition technique. The structures of the one-dimensional tilted carbon nanorods evolve with substrate temperatures, but otherwise identical growth conditions. The crystallographic structures, chemical compositions and bond structures of the tilted carbon nanorods were investigated by using x-ray diffraction, energy dispersive x-ray spectroscopy, x-ray photoelectron spectroscopy and Raman scattering spectroscopy. The cross-sectional SEM image showed that multilayered tilted carbon nanorods were also obtained. The electron field emission (FE) behaviours of the obtained one-dimensional carbon tilted nanorod arrays were greatly improved with the increase in substrate temperature. Meanwhile, the sample with multiple layers of carbon tilted nanorods exhibits better FE behaviours than those with single layer.
