Abstract

We synthesized carbon nanotube (CNT) bridges between Fe nanoparticles by low pressure thermal chemical vapor deposition using etylene gas. At low temperatures, randomly oriented CNTs were dominantly grown with increasing gas pressure. By optimizing the growth conditions, horizontally oriented straight CNTs bridged between Fe particles were obtained under a low pressure of 100 Pa.
