Thiolation and Self-assembly of Carbon Nanotubes

People

Project

We have functionalised single wall carbon nanotubes with thiols, self-assembled the thiolated tubes onto gold electrodes and measured the current-voltage characteristics of the self-assembled SWNT devices.

X-ray photoelectron spectra of unexposed and plasma-exposed SWNTs showing the existence of C-S bonding after plasma exposure

Raman spectra of un-exposed and plasma-exposed SWNTs showing subtle changes in the D to G band and the RBM band
