Abstract

We have examined the device characteristics of solution-processed single-walled carbon nanotube (SWNT) transistors. By using an electrical breakdown, SWNT-field-effect transistors (FETs) exhibited an on/off ratio (I_on/I_off) of 10⁴ and a field-effect mobility of 3.6 cm² V^-1 s^-1 in air, which are comparable to those of other organic FETs. We investigated the detailed mechanism of carrier injection from electrode metals into SWNTs. From the temperature dependence of source-drain current, we evaluated the effective Schottky barrier height for holes to be 170meV.
