High detectivity terahertz radiation sensing using frequency-noise-optimized nanomechanical resonators
Chang Zhang, Eeswar K. Yalavarthi, Mathieu Giroux +6
We achieve high detectivity terahertz sensing using a silicon nitride nanomechanical resonator functionalized with a metasurface absorber. High performances are achieved by strikin…
Demonstration of Frequency Stability limited by Thermal Fluctuation Noise in Silicon Nitride Nanomechanical Resonators
Chang Zhang, Raphael St-Gelais
The frequency stability of nanomechanical resonators (NMR) dictates the performance level of many state-of-the-art sensors (e.g., mass, force, temperature, radiation) that relate a…
Observation of Silicon Nitride Nanomechanical Resonator Actuation Using Capacitive Substrate Excitation
Gengyang Mu, Nikaya Snell, Chang Zhang +5
We observe the actuation of silicon nitride (SiN) nanomechanical resonators by electrical excitation of metal-dielectric-semiconductor (MDS) capacitors on their supporting silicon…
Heat Transport in Silicon Nitride Drum Resonators and its Influence on Thermal Fluctuation-induced Frequency Noise
Nikaya Snell, Chang Zhang, Gengyang Mu +2
Silicon nitride (SiN) drumhead resonators offer a promising platform for thermal sensing due to their high mechanical quality factor and the high temperature sensitivity of their r…
High Resolution Measurement of Near-Field Radiative Heat Transfer enabled by Nanomechanical Resonators
Mathieu Giroux, Chang Zhang, Nikaya Snell +3
Near-field radiative heat transfer (NFHT) research currently suffers from an imbalance between numerous theoretical studies, as opposed to experimental reports that remain, in prop…
Radiative Heat Transfer in Free-Standing Silicon Nitride Membranes
Chang Zhang, Mathieu Giroux, Thea Abdul Nour +1
Free-standing silicon nitride (SiN) mechanical resonators are of central interests in applications such as temperature and mass sensing, and for fundamental optomechanical reasearc…
