Measuring carbon nanotube vibrations using a single-electron transistor as a fast linear amplifier

Yutian Wen, N. Ares, T. Pei, G. A. D. Briggs, E. A. Laird

We demonstrate sensitive and fast electrical measurements of a carbon nanotube mechanical resonator. The nanotube is configured as a single-electron transistor, whose conductance is a sensitive transducer for its own displacement. Using an impedance-matching circuit followed by a cryogenic amplifier, the vibrations can be monitored at radio frequency. The sensitivity of this continuous displacement measurement approaches within a factor 470 of the standard quantum limit.
