Abstract

Single-wall carbon nanotubes (SWCNTs) are ideal structures for studying the transport of electrons in one-dimension and have potential to be used as nanoscale transistors and sensors. Raman scattering from SWCNTs provides an effective and non-destructive means to reveal the remarkable structure, the unusual electronic and photon properties on a single nanotube level. In this study, the SWCNTs are grown between two metallic electrodes with a distance of 2-5 μm, using a laser-assisted chemical vapor deposition method (LCVD). The SWCNTs are precisely located by a motorized XYZ stage with a step resolution of 3.175 μm. The Raman peaks for the radial breathing mode (RBM) and graphitic mode (G mode) are measured, from which the diameter and chirality are analyzed. The RBM mode from these nanotubes is spectroscopically mapped at different spatial coordinates with submicron resolution and the results are compared with those from scanning electron microscopy.
