Abstract
Two kinds of carbon nanotubes, multiwalled bamboo-likeand well-aligned straight ones are obtained on quartz substrate bychemical vapour deposition using Fe-phthalocyanine. The bases of thesenanotubes include nanoparticles with conical and cylindrical shapes,respectively. The former are found in smooth areas and the latter inragged areas. Growth processes of these nanotubes are interpreted to becontrolled by the degree of wetting of liquid metal particles in thoseareas. Strong warping observed in the graphitic shells of straightnanotubes is well rearranged by heat treatment at 2800\\r{}C, giving shellspacing equivalent to the interlayer distance of a turbostratic graphite.
