Single-Walled Carbon nanotubes(SWNTs) have been found to be have a n-type transfer characteristics in vacuum. Reaction of single-salled carbon nanotubes (SWNTs) with molecules having large electron affinity and small ionization energy achieved p-type(TCNQ : Tetracyanoquinodimethane) and n-type(TTF : Tetrathiafulvalene) doping, respectively. Encapsulation of those molecules was carried out inside carbon nanotube under vacuum environment. The simplicity of the synthetic process offers a viable route for the large-scale production of SWNTs with controlled doping states, because of using mat-type SWNT. After encapsulation, TTF- and TCNQ-encapsulated SWNT deposited between electrodes of a bottom gate field effect transistor (FET) fabricated on Si-wafer substrate and investigate their electronic transport properties. FET character depends on changing gate voltages, Near IR and Raman were measured to elucidate charge transfer between those molecules and SWNTs.
