Noncontact friction in ultracoherent nanomechanical resonators near dielectric materials
Amirali Arabmoheghi, Alessio Zicoschi, Guillermo Arregui +4
Micro- and nanomechanical resonators are emerging as promising platforms for quantum technologies, precision sensors and fundamental science experiments. To utilize these devices f…
Strained crystalline nanomechanical resonators with ultralow dissipation
Alberto Beccari, Diego A. Visani, Sergey A. Fedorov +4
In strained mechanical resonators, the concurrence of tensile stress and geometric nonlinearity dramatically reduces dissipation. This phenomenon, dissipation dilution, is employed…
Hierarchical tensile structures with ultralow mechanical dissipation
Mohammad J. Bereyhi, Alberto Beccari, Robin Groth +4
Structural hierarchy is found in myriad biological systems and has improved man-made structures ranging from the Eiffel tower to optical cavities. Hierarchical metamaterials utiliz…
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…
