Thermoelectric Scanning Gate Interferometry on a Quantum Point Contact
B. Brun, F. Martins, S. Faniel +11
We introduce a new scanning probe technique derived from scanning gate microscopy (SGM) in order to investigate thermoelectric transport in two-dimensional semiconductor devices. T…
Wigner and Kondo physics in quantum point contacts revealed by scanning gate microscopy
B. Brun, F. Martins, S. Faniel +11
Quantum point contacts exhibit mysterious conductance anomalies in addition to well known conductance plateaus at multiples of 2e^2/h. These 0.7 and zero-bias anomalies have been i…
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…
Imaging Coulomb Islands in a Quantum Hall Interferometer
B. Hackens, F. Martins, S. Faniel +7
In the Quantum Hall regime, near integer filling factors, electrons should only be transmitted through spatially-separated edge states. However, in mesoscopic systems, electronic t…
Fluorescent oxide nanoparticles adapted to active tips for near-field optics
A. Cuche, B. Masenelli, G. Ledoux +5
We present a new kind of fluorescent oxide nanoparticles with properties well suited to active-tip based near-field optics. These particles with an average diameter in the range 5-…
Surface Plasmon mediated near-field imaging and optical addressing in nanoscience
A. Drezet, A. Hohenau, J. R. Krenn +2
We present an overview of recent progress in plasmonics. We focus our study on the observation and excitation of surface plasmon polaritons (SPPs) with optical near-field microscop…
