Electrical transport and confocal Raman studies of electrochemically modified individual carbon nanotubes

Electrochemical coating of individual single-walled carbon nanotubes (SWCNTs) with thin films obtained via oxidative coupling of an amine or reductive coupling of an aromatic diazonium salt is reported. The same SWCNTs have been characterized before and after modification by electrical transport measurements and confocal Raman spectroscopy (see Figure, electrode structure white, background dark blue, and SWCNTs light blue to red).
