Dynamics of Small Elastic Systems in Fluid: Tension and Nonlinearity
… for systems including cantilevers and doubly clamped beams. Building on these advances, this work extends the theory of doubly clamped beams with an arbitrary amount of tension. Both the driven and stochastic dynamics of a doubly clamped beam are explored. The driven dynamics are …

Nanoelectronic and nanomechanical devices for low temperature applications
… and the superfluid phases of helium-4. The doubly clamped beams had a cross section of 100nm by 100nm and were tested in length variants between 15um to 50um, The flexural resonance between 1MHz and 10MHz in response to the helium temperature dependent properties showed an encouraging …

Tailoring the Geometry of Micron Scale Resonators to Overcome Viscous Damping
… of the mechanical oscillations of micron scale beams in a viscous fluid, such as water, is an open challenge of direct relevance to the development of future technologies. We study the stochastic dynamics of doubly-clamped micron scale beams in a viscous fluid driven by Brownian motion. We use a …

The mode-dependent dynamics of nonlinear nanomechanical resonators
… long and slender NEMS resonator in the form of a doubly-clamped beam in tension. Using nonlinear Euler-Bernoulli beam theory, the geometric nonlinearity due to the stretching of the neutral axis is considered. We extensively explore simplifications in using a Galerkin discretization of the …

Suspended Gate Silicon Nanodot Memory
… in this novel device is the introduction of a doubly-clamped beam as a movable control gate, in which through this element, the programming and erasing operations take place. To understand the behaviour of the doubly-clamped beam structure, it is analysed by using analytical models such as the …
