AbstractStructural phase transformation from multiwalled carbon nanotubes to nanocrystalline diamond by hydrogen plasma posttreatment was carried out. Ultrahigh equivalent diamond nucleation density above 10(11) nuclei/cm(2) was easily obtained. The diamond formation and growth mechanism was proposed to be the consequence of the formation of sp(3) bonded amorphous carbon clusters. The hydrogen chemisorption on curved graphite network and the energy deposited on the carbon nanotubes by continuous impingement of activated molecular or atomic hydrogen are responsible for the formation of amorphous carbon matrix. The diamond nucleates and grows in the way similar to that of diamond CVD processes on amorphous carbon films. The present method of hydrogen treatment provides a controllable way for the CVD of high quality diamond films.
