概述：

　　Electron imaging and Raman spectroscopy are established techniques for viewing and analysing carbon nanotubes. Performing these two techniques usually requires the sample being transferred between a scanning electron microscope (SEM) and a Raman spectrometer. This application note illustrates the advantages of Renishaw’s structural and chemical 　　analyser (SCA) for simultaneous secondary electron imaging and Raman spectroscopy of single-wall carbon nanotubes (SWNTs).

　　介绍：

　　Since their first observation by Sumio Iijima in 1991,1 carbon nanotubes have attracted intense scientific interest due to their extraordinary electronic, thermal, and mechanical properties. The structure can be visualised as a graphite layer rolled up into a seamless cylinder, with each end either open or capped with half a fullerene molecule. The points at which the rolled up graphite sheet are connected define the tube’s diameter and chirality, which, in turn, govern its properties.
