Modification of the electrical characteristics of single wall carbon nanotubes through selective functionalization

C. Ni; Jayanta Chattopadhyay; W. E. Billups; Prabhakar R. Bandaru

We propose a scheme of carrier doping single-walled nanotubes, which involves the selective addition of organic functional groups. It is shown that electron transfer from/to the attached group can be used to diminish/enhance the intrinsic, ambient, p-type conduction. Dodecyl functional group attachment, in addition to compensating the positive hole carriers, has been shown to reduce hysteretic behavior in electrical transport.
