    Abstract

    Triton X-100 is used as a surfactant to disperse carbon nanotube (CNT) bundles. Its influence on the transfer characteristics of carbon nanotube field-effect transistors (CNTFETs) fabricated with the dispersed CNTs by the AC dielectrophoresis technique has been studied. We find that the surfactant at the interface between the CNTs and Au electrodes can change the work function of the electrodes and therefore convert the CNTFETs from typical p-type to having ambipolar characteristics. The adsorbed surfactant between the CNTs and SiO2 results in a significant hysteresis in the transfer characteristics of the CNTFETs.
