Actuation and mapping of SAW-induced high-frequency wavefields on suspended graphene membranes
Hande N. Açıkgöz, Dong Hoon Shin, Inge C. van der Knijff +5
High frequency acoustic devices based on two-dimensional (2D) materials are unique platforms to design and manipulate the spatiotemporal response of acoustic waves for next-generat…
Optimizing Cladding Elasticity to Enhance Sensitivity in Silicon Photonic Ultrasound Sensors
R. Tufan Erdogan, Georgy A. Filonenko, Stephen J. Picken +2
Ultrasound is widely used in medical imaging, and emerging photo-acoustic imaging is crucial for disease diagnosis. Currently, high-end photo-acoustic imaging systems rely on piezo…
Microsphere-assisted generation of localized optical emitters in 2D hexagonal boron nitride
Xiliang Yang, Dong Hoon Shin, Kenji Watanabe +3
Crystal defects in hexagonal boron nitride (hBN) are emerging as versatile nanoscale optical probes with a wide application profile, spanning the fields of nanophotonics, biosensin…
Finite Element-based Nonlinear Dynamic Optimization of Nanomechanical Resonators
Zichao Li, Farbod Alijani, Ali Sarafraz +4
Nonlinear dynamic simulations of mechanical resonators have been facilitated by the advent of computational techniques that generate nonlinear reduced order models (ROMs) using the…
The graphene squeeze-film microphone
M. P. Abrahams, J. Martinez, P. G. Steeneken +1
Most microphones operate by detecting the sound-pressure induced motion of a membrane. In contrast, here we introduce a microphone that operates by monitoring the sound-pressure-in…
Tuning dissipation dilution in 2D material resonators by MEMS-induced tension
M. P. F. Wopereis, N. Bouman, S. Dutta +3
Resonators based on two-dimensional (2D) materials have exceptional properties for application as nanomechanical sensors, which allows them to operate at high frequencies with high…
