Alberto MartÃn-Pérez, Peter G. Steeneken, Farbod Alijani
Graphene resonators exhibit unique mechanical and electrical properties, making them promising candidates for next-generation sensing applications. Here, we introduce an optomechan…
Magnomechanical Coupling in Suspended 2D van der Waals Ferromagnets
Ritesh Das, Alvaro Bermejillo-Seco, Herre S. J. van der Zant +2
Magnomechanical systems provide a promising route for exploring coherent hybrid magnon-phonon interactions and hybrid information processing, but their realization has so far been…
Experimental Quantification of Nonlinear Mode Coupling in Nanomechanical Resonators using Multi-tone Excitation
Chris F. D. Wattjes, Zichao Li, Minxing Xu +3
Nonlinear modal interactions in resonant systems govern a wide range of phenomena, with broad relevance across modern physics and engineering. Yet, experimentally determining the s…
Capacitive Pixelated CMOS Electronic Nose
M. A. Basyooni-M. Kabatas, Tao Shen, Kai Betlem +5
Although some of the human senses can nowadays be replaced by low-cost electronic sensors such as microphones and image sensors, a compact low-cost electronic nose (E-nose) remains…
Cascade of Modal Interactions in Nanomechanical Resonators with Soft Clamping
Zichao Li, Minxing Xu, Richard A. Norte +3
We uncover a chain of nonlinear modal interactions in softly clamped nanostring resonators. The process involves the sequential coupling of five mechanical modes, during frequency…
