AFM/Raman of Carbon Nanotube

Chemical Mapping Using Raman Microscopy

AFM Raman of CNT Nanowire on Silicon

The frequency of the Raman band at 1575cm-1 indicates whether

the carbon nanotube is at a metallic, semi-conductor, or insulating

orientation. Clear difference is observed between the high quality

nanotube (red) and the disordered material (green).
