Molecularly Thin Polyaramid Nanomechanical Resonators
Hagen Gress, Cody L. Ritt, Inal Shomakhov +8
Two-dimensional polyaramids exhibit strong hydrogen bonding to create molecularly thin nanosheets analogous to graphene. Here, we report the first nanomechanical resonators made ou…
Theoretical modeling of the dynamic range of an elastic nanobeam under tension with a geometric nonlinearity
N. W. Welles, M. Ma, K. L. Ekinci +1
A theoretical description of the weakly nonlinear and mode-dependent dynamics of a nanoscale beam that is under intrinsic tension is developed. A full analysis of the dynamic range…
Multistability and Noise-Induced Transitions in Dispersively-Coupled Nonlinear Nanomechanical Modes
David Allemeier, İsmet İnönü Kaya, M. Selim Hanay +1
We study the noisy dynamics of two coupled bistable modes of a nanomechanical beam. When de-coupled, each driven mode obeys the Duffing equation of motion, with a well-defined bist…
Mode-Dependent Scaling of Nonlinearity and Linear Dynamic Range in a NEMS Resonator
M. Ma, N. Welles, O. Svitelskiy +5
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…
