Offer Description

The postdoctoral researcher will integrate into the research activities of the Quantum Nanoelectronics and Spectroscopy team at the Institut Néel. Their role will involve experimental studies ranging from the fabrication to the very low-temperature measurement of graphene-based superconducting devices operating in the quantum Hall effect regime.

The mission consists in fabricating encapsulated graphene devices and coupling these quantum Hall effect edge channels to superconducting electrodes to realize Josephson junctions. Certain phases of the quantum Hall effect have the specific characteristic of being spin-polarized. The scientific objective will be to study the unconventional nature of the superconductivity induced in these spin-polarized edge channels through electrical conductivity measurements.

The postdoctoral researcher will fabricate graphene samples, from exfoliation and encapsulation to contact patterning using electron-beam lithography and metal deposition via standard cleanroom processes. They will carry out a systematic study at very low temperatures of hybrid superconductor/quantum Hall effect devices, such as Josephson junctions, through current-voltage characteristic measurements under high magnetic fields. They will participate in the supervision of PhD students and master students.
