Specific Heat of Thin Phonon Cavities at Low Temperature: Very High Values Revealed by ZeptoJoule Calorimetry

Adib Tavakoli, Kunal J. Lulla, Tuomas Puurtinen +4

Specific heat of phonon cavities is investigated in order to analyse the effect of phonon confinement on thermodynamic properties. The specific heat of free standing very thin SiN…

Mapping nanoscale dynamic properties of suspended and supported multi-layer graphene membranes via contact resonance and ultrasonic scanning probe microscopies

Marta Mucientes, Robert McNair, Adrian Peasey +5

Graphene (GR) remarkable mechanical and electrical properties - such as its Young's modulus, low mass per unit area, natural atomic flatness and electrical conductance - would make…

The Universality of Thermal Transport in Amorphous Nanowires at Low Temperatures

Adib Tavakoli, Christophe Blanc, Hossein Ftouni +4

Thermal transport properties of amorphous materials at low temperatures are governed by the interaction between phonons and localized excitations referred to as tunneling two level…

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.…

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…

Audio mixing in a tri-port nano-electro-mechanical device

M. Defoort, K. Lulla, J. -S. Heron +3

We report on experiments performed on a cantilever-based tri-port nano-electro-mechanical (NEMS) device. Two ports are used for actuation and detection through the magnetomotive sc…
