Tunable Micro- and Nanomechanical Resonators

Advances in micro- and nanofabrication technologies have enabled the development of novel micro- and nanomechanical resonators which have attracted significant attention due to their fascinating physical properties and growing potential applications. In this review, we have presented a brief overview of the resonance behavior and frequency tuning principles by varying either the mass or the sti...

Damping mechanisms in high-Q micro and nanomechanical string resonators

Phonon Tunneling Loss Solver for Micro- and Nanomechanical Resonators

Microand nanoscale mechanical resonators have emerged as ubiquitous devices for application in a wide range of technical disciplines including communications, sensing, metrology, and fundamental scientific endeavors. In many instances the performance of these devices is limited by the deleterious effects of mechanical damping. To further compound this limitation, the quantitative understanding ...

Quantized nanomechanical resonators

are well suited to such explorations. Their dimensions not only make them susceptible to local forces, but also make it possible to integrate and tightly couple them to a variety of interesting electronic structures, such as solid-state twolevel systems (quantum bits, or qubits), that exhibit quantum mechanical coherence. In fact, the most-studied systems, nanoresonators coupled to various supe...

Damping of nanomechanical resonators.

We study the transverse oscillatory modes of nanomechanical silicon nitride strings under high tensile stress as a function of geometry and mode index m≤9. Reproducing all observed resonance frequencies with classical elastic theory we extract the relevant elastic constants. Based on the oscillatory local strain we successfully predict the observed mode-dependent damping with a single frequency...
