Title: Effect of the electric field of the anode sheath on the growth of aligned carbon nanotubes in a glow discharge

Abstract

Arrays of aligned carbon nanotubes on silicon substrates were grown in the anode sheath of a dc glow discharge. In order to clarify the role of the electric field in the growth of nanotubes, numerical simulations of charged particle transport in the anode sheath were carried out in the drift-diffusion approximation. The distributions of the charged particle density and electric field are obtained. Possible mechanisms whereby the electric field influences the growth of aligned carbon nanotubes are analyzed. It is found that the nanotubes grow in the region in which the electric field is enhanced due to the depletion of positive ions in the anode sheath.

  • Effects of magnetic-field introduction and micro/macroelectric fields in a plasma sheath on the carbon nanotube growth are investigated by employing a cylindrical magnetron-type radio-frequency (rf) plasma-enhanced chemical-vapor deposition method. The cross-field magnetic-field application is accompanied by the high-density plasma generation and the reduction of direct impinge of high-energy ions to a rf electrode substrate, achieving the carbon nanotube formation without harmful sputtering phenomenon. It is found that microelectric fields in the plasma sheath are useful in the sense of substrate pretreatment and macroelectric fields have to be optimized in order to obtain well-aligned and refined nanotube structures in a largemore » area. These experimental results lead to putting into practice of quite simple methods for the site-selected carbon nanotube growth in a relatively large area, so-called substrate-scratching method and mesh-masking method.« less
  • The results of a parametric study on the growth of vertically aligned carbon nanofibers (CNFs) by high-density inductively coupled plasma (ICP) chemical-vapor deposition are reported. We investigated the mechanisms that cause the detachment of CNFs during the growth process by high-density plasma-enhanced chemical-vapor deposition with high substrate bias voltage and atomic hydrogen concentration. A simplified model, combining the Child law for sheath field, floating sphere model for field enhancement at the fiber tip and electric-field screening effect, was employed to estimate the detachment electrostatic force on individual CNFs induced by plasma sheath electric field. The force was found to increasemore » with substrate bias voltage, bias current, and lengths of CNFs, consistent with the experimental observations that CNFs density decreases with ICP power, bias power, and growth time. However, the magnitude of the electrostatic force per se cannot explain the detachment phenomena. The other factor is believed to be the ion-assisted etch of CNFs by atomic hydrogen during the growth process since it was observed that the lower end of CNFs formed earlier in the synthesis process became thinner than the tip end.« less
  • Multiwalled-carbon nanotubes (MWCNTs) are grown on top of vertically aligned carbon nanofibers (VACNFs) via microwave plasma-enhanced chemical vapor deposition (MPECVD). The VACNFs are first grown in a direct-current plasma-enhanced chemical vapor deposition reactor using nickel catalyst. A layer of carbon-silicon materials is then deposited on the VACNFs and the nickel catalyst particle is broken down into smaller nanoparticles during an intermediate reactive-ion-plasma deposition step. These nickel nanoparticles nucleate and grow MWCNTs in the following MPECVD process. Movable-probe measurements show that the MWCNTs have greatly improved field-emission properties relative to the VACNFs
  • Based on the well-accepted electron-shading theory during plasma processing, we designed microstructures to control the local built-in electric-field on the substrate surface. The distortion magnitude of the electric-field is largest near the sidewalls of the microstructures, creating a horizontal electric-field in this region. We showed that the horizontally aligned carbon nanotubes (CNTs) were grown by making use of this built-in electric-field during the plasma-enhanced chemical vapor deposition process, with a tactical choice of geometries and materials of the microstructures on the substrate. This technique opens up a way to selectively and controllably grow horizontally aligned CNTs on the substrate surface.
