Carbon nanotubes (CNTs) are nonlinear high-Q resonators with strong coupling to single-electron tunneling. This chapter begins by describing several methods to detect the flexural motion of a CNT resonator. Next, it illustrates how single-electron tunneling in quantum dot CNT resonators leads to sharp dips in the mechanical resonance frequency and significant damping. It discusses four different contributions to the nonlinear oscillation of a CNT resonator: beam-like mechanical nonlinearity, nonlinearity due to gate-induced mechanical tension, electrostatic nonlinearity, and nonlinearity due to single-electron tunneling, and provide quantitative estimates of their strengths. Finally, it shows how the large response of the resonance frequency of a CNT resonator to a change in gate voltage or tension makes CNT resonators ideally suited for parametric excitation and for studying the coupling between different mechanical modes.

Keywords:   carbon nanotube, nonlinearity, flexural motion, single-electron tunnelling, quantum dot, mode coupling, parametric excitation, tension, damping, frequency tuning
