摘要：

We describe the first elaboration of carbon nanotube tips (CN-tips) by the sol-gel technique. The CN-tips consist of single carbon nanotubes (CNs) or bundles sheathed by a nanometric layer of TiO2 fixed to the apex of a W base tip and oriented along its major axis. The straight-forward method potentially permits low cost batch fabrication. Structural analysis has been realized by transmission electron microscopy (TEM). These CN-tips are interesting for applications in applied surface science such as field emission (FE) sources and near field microscopy probes. A first field emission study has also been carried out showing that the TiO2 layer does not block FE. Relatively stable emission at voltages usual to FE from CNs at up to 0.8 muA current were obtained. (C) 2003 Elsevier B.V. All rights reserved.
