Abstract

The effect of the nickel as a catalyst particle in the growth of carbon nanotubes (CNT) by plasma enhanced chemical vapor deposition was investigated. The presence of metastable carbide Ni ₃C at the tip of the tubes was revealed by the high resolution transmission electron microscopy of the nickel particle. It was observed that the presence of Ni ₃C had reduced the mobility of C atoms. The structure of the CNT walls and number of bamboolike intersect were determined from the shape and size of the catalytic particle.
