这封信概述了一个模型来解释化学气相沉积纳米管的催化生长。它提出，它们的形成和生长是其他已知过程的延伸，其中石墨结构在中等温度下通过有机前体的分解在金属表面上形成。重要的是，该模型还指出，产生的碳的形式取决于催化反应的物理尺寸。实验数据显示纳米管的直径与催化剂颗粒的尺寸相关。纳米管的稳定性作为纳米管的类型，长度和直径的函数也通过理论计算进行了研究。(C)1999 Elsevier Science B.V.保留所有权利。
This Letter outlines a model to account for the catalyzed growth of nanotubes by chemical vapor deposition. It proposes that their formation and growth is an extension of other known processes in which graphitic structures form over metal surfaces at moderate temperatures through the decomposition of organic precursors. Importantly, the model also states that the form of carbon produced depends on the physical dimensions of the catalyzed reactions. Experimental data are presented that correlate nanotube diameters to the size of the catalyst particles. Nanotube stability as a function of nanotube type, length and diameter are also investigated through theoretical calculations. (C) 1999 Elsevier Science B.V. All rights reserved.
