摘要：

Two kinds of carbon nanotubes, multiwalled bamboo-like and well-aligned straight ones are obtained on quartz substrate by chemical vapour deposition using Fe-phthalocyanine. The bases of these nanotubes include nanoparticles with conical and cylindrical shapes, respectively. The former are found in smooth areas and the latter in ragged areas. Growth processes these nanotubes are interpreted to be controlled by the degree of wetting of liquid metal particles in those areas. Strong warping observed in the graphitic shells of straight nanotubes is well rearranged by heat treatment at 2800degreesC, aiving shell spacing equivalent to the interlayer distance of a turbostratic graphite.
