Single Carbon Nanotube Transistor at GHz Frequency
Single Carbon Nanotube Transistor at GHz Frequency
We report on microwave operation of top-gated single carbon nanotube transistors. From transmission measurements in the 0.1ā1.6 GHz range, we deduce device transconductance gm and gateānanotube capacitance Cg of micro- and nanometric devices. A large and frequency-independent gm ā¼ 20 Ī¼S is observed on short devices, which meets the best ā¦
