Reduction of intrinsic losses in nanomechanical silicon nitride resonators through thermal treatment in ultrahigh vacuum
Nicola Cavalleri, Ariane Giesriegl, Robert G. West +7
Since the discovery of dissipation dilution, silicon nitride (SiN) nanomechanical resonators have set the benchmark for ultracoherent mechanical systems, with geometry and strain e…
HF Etching and Silanization: Evidence for the Role of Surface Hydroxyl Groups in Silicon Nitride Resonator Loss
Ariane Giesriegl, Nicola Cavalleri, Robert West +4
Silicon nitride nanomechanical resonators are central to sensing, quantum technologies, and fundamental physics experiments due to their exceptional mechanical quality fact…
Determination of the intrinsic mechanical quality factor in high-stress silicon nitride resonators
Geena Benga, Vincent Dumont, Wei Wang +6
Recent advances in silicon nitride nanomechanical resonators have pushed mechanical quality factors to ultra-high values by combining stress-induced dissipation dilution with mode-…
Picogram-Level Nanoplastic Analysis with Nanoelectromechanical System Fourier Transform Infrared Spectroscopy: NEMS-FTIR
Jelena Timarac-PopoviÄ, Johannes Hiesberger, Eldira Å esto +5
We present a photothermal infrared spectroscopy-based approach for the chemical characterization and quantification of nanoplastics. By combining the high sensitivity of nanoelectr…
