Description du sujet de thèse

The expected role of the researcher for this position is to fabricate Josephson junctions using graphene contacted by superconducting electrodes and equipped with a quantum point contact. The latter will allow control over the number of quantum Hall edge channels contributing to the supercurrent. The junctions will be characterized through magnetotransport measurements at very low temperatures.
Activities:
- Fabrication of van der Waals heterostructures in a cleanroom environment.
- Magnetotransport measurements.
- Data analysis and writing of scientific articles.
Expected skills:
- Superconductor physics (advanced level)
- Python programming (basic level)
- Cryogenics (basic level)

Contexte de travail

The candidate will work in the Institut Néel's QuNES team, under the supervision of Benjamin Sacépé, as part of a European ERC project.
The Institut NEEL, UPR 2940 CNRS, is one of the largest French national research institutes for fundamental research in condensed matter physics enriched by interdisciplinary activities at the interfaces with chemistry, engineering and biology. The laboratory is related to the CNRS Physique. It is located in the heart of a unique scientific, industrial and cultural environment. It is part of one of Europe's biggest high-tech environment in micro- and nanoelectronics, right next to the French Alpes.
The Institut NEEL is a CNRS laboratory. CNRS is a public, scientific and technological organisation. The core mandate is to identify, carry out ou have carried out, either alone or with partners, all research that advances science or contributes to the country's economic, social, and cultural progress. Internationally recognised for the excellence of its scientific research, the CNRS is a reference in the world of research and development, as well as for the general public.

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.

Contraintes et risques

Working near an intense magnetic field.
