Abstract
This Letter outlines a model to account for the catalyzed growth of nanotub es by chemical vapor deposition. It proposes that their formation and growt h is an extension of other known processes in which graphitic structures fo rm over metal surfaces at moderate temperatures through the decomposition o f organic precursors. Importantly, the model also states that the form of c arbon produced depends on the physical dimensions of the catalyzed reaction s. Experimental data are presented that correlate nanotube diameters to the size of the catalyst particles. Nanotube stability as a function of nanotu be type, length and diameter are also investigated through theoretical calc ulations. (C) 1999 Elsevier Science B.V. All rights reserved.
