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.
