FUNCTION
We have an opening for a two-year postdoctoral position, for work in a collaboration between C2N, Institut Néel and the Grenoble High Magnetic Field Laboratory within the ANR project THERMES-2D. The aim of the project is to explore correlated phases of matter through innovative thermodynamic measurements, such as heat capacity and entropy. The successful candidate will join the group “Physics and Technology of Nanostructure and Quantum Systems” in the team of Ulf Gennser. The central part of his/her work will be to develop novel, thermodynamic tools based on GaAs/AlGaAs 2-dimensional electron gases (2DEGs), which will be applied to investigating the specific heat in the fractional quantum Hall effect. She/he will be highly involved in the fabrication and measurements of membrane 2DEGs using the nano fabrication facilities of C2N.

QUALIFICATIONS AND EXPERIENCE
Candidates should hold a Ph.D. in experimental condensed matter physics or equivalent. A good technical background in semiconductor sample processing is crucial (e-beam lithography, lift-off techniques, etch techniques ...). Experience with transport experiments, low-temperature experiments, as well as a knowledge in mesoscopic physics and 2-dimensional electron gases would
be appreciated assets.

The position is open from February 1st, 2021.

Applications (CV + two letters of recommendation + short research summary) should be sent by email to ulf.gennser@c2n.upsaclay.fr

Post-Doc

The lighting and signalling functions in cars ensure the safety of motorists and pedestrians. With the advent of new light sources such as LEDs and, in the longer term, lasers, new lighting and signalling systems will emerge. In particular, holographic displays are opening up innovative perspectives in this field of application. However, current holographic systems lack compactness due to the extension of the light source of the holographic plate. A large area planar source solution has been proposed recently, based on substrate guided optics technologies.

The aim of this postdoctoral fellowship is to experimentally demonstrate this planar source, which comprises a SiN-on-silica guide array (already fabricated), functionalized by silver plasmonic nanoantennas. The postdoc will follow the process of functionalization of the guides (by electron lithography, silver lift-off and encapsulation), then optically characterize the structures and compare the emission properties of the structure with numerical predictions.

Profile required: education in optics/photonics; knowledge of nanofabrication in clean room (for process monitoring) ; good knowledge of optical characterisation; basic knowledge of optical simulation
