Clamp-tapering increases the quality factor of stressed nanobeams
Mohammad J. Bereyhi, Alberto Beccari, Sergey A. Fedorov +5
Stressed nanomechanical resonators are known to have exceptionally high quality factors () due to the dilution of intrinsic dissipation by stress. Typically, the amount of dissi…

Sergey A. Fedorov, Nils J. Engelsen, Amir H. Ghadimi +4
Mechanical resonators with high quality factors are of relevance in precision experiments, ranging from gravitational wave detection and force sensing to quantum optomechanics. Bea…
Strain engineering for ultra-coherent nanomechanical oscillators
Amir H. Ghadimi, Sergey A. Fedorov, Nils J. Engelsen +4
Elastic strain engineering utilizes stress to realize unusual material properties. For instance, strain can be used to enhance the electron mobility of a semiconductor, enabling mo…
Dissipation engineering of high-stress silicon nitride nanobeams
A. H. Ghadimi, D. J. Wilson, T. J. Kippenberg
High-stress SiN nanoresonators have become an attractive choice for electro- and optomechanical devices. Membrane resonators can achieve quality factor () - frequency ($…
