Statistical Properties of a Fluctuation-Driven Nanomechanical Duffing Resonator
Monan Ma, Nathan Welles, Johnathon Barbish +5
We investigate the fluctuating nonlinear dynamics of multiple modes of a nanomechanical doubly clamped beam resonator. Each mode is driven by Gaussian force noise centered around t…
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…
Multi-mode Brownian Dynamics of a Nanomechanical Resonator in a Viscous Fluid
H. Gress, J. Barbish, C. Yanik +7
Brownian motion imposes a hard limit on the overall precision of a nanomechanical measurement. Here, we present a combined experimental and theoretical study of the Brownian dynami…
Electrothermal Actuation of NEMS Resonators: Modeling and Experimental Validation
Monan Ma, Kamil L. Ekinci
We study the electrothermal actuation of nanomechanical motion using a combination of numerical simulations and analytical solutions. The nanoelectrothermal actuator structure is a…
The dynamics of an externally driven nanoscale beam that is under high tension and immersed in a viscous fluid
Johnathon Barbish, Chaoyang Ti, Kamil Ekinci +1
We explore the dynamics of a nanoscale doubly-clamped beam that is under high tension, immersed in a viscous fluid, and driven externally by a spatially varying drive force. We dev…
