Slippage and boundary layer probed in an almost-ideal gas by a nano-mechanical oscillator
M. Defoort, K. J. Lulla, T. Crozes +3
We have measured the interaction between He gas at 4.2K and a high-quality nano-electro-mechanical string device for its first 3 symmetric modes (resonating at 2.2MHz, 6.…
Probing Bogoliubov quasiparticles in superfluid He with a 'vibrating-wire like' MEMS device
M. Defoort, S. Dufresnes, S. L. Ahlstrom +11
We have measured the interaction between superfluid He-B and a micro-machined goalpost-shaped device at temperatures below . The measured damping follows well the the…
In-situ comprehensive calibration of a tri-port nano-electro-mechanical device
E. Collin, M. Defoort, K. Lulla +5
We report on experiments performed in vacuum and at cryogenic temperatures on a tri-port nano-electro-mechanical (NEMS) device. One port is a very non-linear capacitive actuation,…
Modal "self-coupling" as a sensitive probe for nanomechanical detection
M. Defoort, K. J. Lulla, C. Blanc +3
We present a high-sensitivity measurement technique for mechanical nanoresonators. Due to intrinsic nonlinear effects, different flexural modes of a nanobeam can be coupled while d…
The thermal conductivity of silicon nitride membranes is not sensitive to stress
Hossein Ftouni, Christophe Blanc, Dimitri Tainoff +6
We have measured the thermal properties of suspended membranes from 10 K to 300 K for two amplitudes of internal stress (about 0.1 GPa and 1 GPa) and for two different thicknesses…
