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…
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…
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…
