Mode-dependent scaling of nonlinearity and linear dynamic range in a NEMS resonator
Mode-dependent scaling of nonlinearity and linear dynamic range in a NEMS resonator
Even a relatively weak drive force is enough to push a typical nanomechanical resonator into the nonlinear regime. Consequently, nonlinearities are widespread in nanomechanics and determine the critical characteristics of nanoelectromechanical systems (NEMS) resonators. A thorough understanding of the nonlinear dynamics of higher eigenmodes of NEMS resonators would be beneficial …
