We report high-performance short channel pentacene field effect transistor (FET) using carbon nanotube aligned array electrodes. The devices show field effect mobility of up to 0.65 cm(2)/Vs and current on-off ratio of up to 1.7 x 10(6), which is the best for sub-micron pentacene FETs. The calculated cutoff frequency (f(c)) of the devices is up to 211 MHz which is among the best reported f(c) for organic transistors. The high performance of our short channel FET is attributed to improved charge injections from the aligned array carbon nanotube electrodes into the pentacene.
