Experimental observation of nanoscale radiative heat flow due to surface plasmons in graphene and doped silicon
P. J. van Zwol, S. Thiele, C. Berger +2
Owing to its two dimensional electronic structure, graphene exhibits many unique properties. One of them is a wave vector and temperature dependent plasmon in the infrared range. T…
Fast heat flux modulation at the nanoscale
P. J. van Zwol, K. Joulain, P. Ben Abdallah +2
We introduce a new concept for electrically controlled heat flux modulation. A flux contrast larger than 10 dB is expected with switching time on the order of tens of nanoseconds.…
Viscous cavity damping of a microlever in a simple fluid
A. Siria, A. Drezet, F. Marchi +3
We consider the problem of oscillation damping in air of a thermally actuated microlever as it is gradually approached towards an infinite wall in parallel geometry. As the gap is…
Casimir force measurements in Au-Au and Au-Si cavities at low temperature
J. Laurent, H. Sellier, A. Mosset +2
We report on measurements of the Casimir force in a sphere-plane geometry using a cryogenic force microscope to move the force probe in situ over different materials. We show how t…
X-ray pushing of a mechanical microswing
A. Siria, M. S. Rodrigues, O. Dhez +11
Nanoelectromechanical Systems (NEMS) are among the best candidates to measure interactions at nanoscale [1-6], especially when resonating oscillators are used with high quality fac…
Large variation in the boundary-condition slippage for a rarefied gas flowing between two surfaces
J. Laurent, A. Drezet, H. Sellier +2
We study the slippage of a gas along mobile rigid walls in the sphere-plane confined geometry and find that it varies considerably with pressure. The classical no-slip boundary con…
Imaging Electron Wave Functions Inside Open Quantum Rings
F. Martins, B. Hackens, M. G. Pala +8
Combining Scanning Gate Microscopy (SGM) experiments and simulations, we demonstrate low temperature imaging of electron probability density in embedded mesoscopic…
Giant slip lengths of a simple fluid at vibrating solid interfaces
A. Drezet, A. Siria, J. Chevrier +1
It has been shown recently [PRL 102, 254503 (2009)] that in the plane-plane configuration a mechanical resonator vibrating close to a rigid wall in a simple fluid can be overdamped…
Imaging and controlling electron transport inside a quantum ring
B. Hackens, F. Martins, T. Ouisse +7
Traditionally, the understanding of quantum transport, coherent and ballistic1, relies on the measurement of macroscopic properties such as the conductance. While powerful when cou…
Negative Backaction Noise in Interferometric Detection of a Microlever
J. Laurent, A. Mosset, O. Arcizet +3
Interferometric detection of mirror displacements is intrinsically limited by laser shot noise. In practice, however, it is often limited by thermal noise. Here we report on an exp…
Plasmons enhance near-field radiative heat transfer for graphene-covered dielectrics
V. B. Svetovoy, P. J. van Zwol, J. Chevrier
It is shown that a graphene layer on top of a dielectric slab can dramatically influence the ability of this dielectric for radiative heat exchange. Effect of graphene is related t…
Tuning near field radiative heat flux through surface excitations with a metal insulator transition
P. J. van Zwol, L. Ranno, J. Chevrier
The control of heat flow is a formidable challenge due to lack of good thermal insulators. Promising new oppor-tunities for heat flow control were recently theoretically discovered…
