The data are interpreted as tightly wound, single-wall, coiled carbon nanotubes with an interspire distance of 0.34 nm as the distance between graphene layers in graphite or the distance of single-wall carbon nanotubes in ropes 关键词: carbon nanotubes;graphite;scanning tunnelling microscopy;transmission electron microscopy;tightly wound C-nanotubes;single-wall C-nanotubes;STM;scanning tunnelling microscopy;hydrocarbon catalytic cracking;axial periodicity;interspire distance;graphene layers distance;graphite;nanotube ropes;TEM;transmission electron microscopy;C
