We have grown carbon nanotubes (CNTs) with a microwave plasma enhanced chemical vapor deposition (MPECVD) method, which has been regarded as one of the most promising candidates for the synthesis of CNTs. We have used argon (Ar) and hydrogen (H2) gas and acetylene (C2H2) as precursor for the growth of CNTs. Ni catalytic layer (10 nm thick) were deposited on the Ti coated Si substrate by RF magnetron sputtering method. In this work, we report the effects of heat treatment on the growth of CNTs, in which we have pretreated the Ni catalytic layer in different temperature (600, 650, and 700 ℃) and moderate microwave power (400W). We investigated the effect of pretreatment temperate of the Ni catalyst layer on the growing characteristics of MWCNTs. Adhesion of Ni (10 nm) is shown to influence the growth characteristics with Ni used as active catalysts. The images show Ni catalytic layer diameter and density are varied dependent on their pretreatment conditions. In order to determine the properties of CNTs, we performer scanning electron microscope(SEM), transmission electron microscopy(TEM), atomic force microscopy(AFM), and X-ray photoelectron spectroscopy(XPS) analysis.
