Welcome!

I study the electronic properties of two dimensionnal materials, in particular graphene. I am interested in using this material to build hybrid quantum systems.

A gate-tunable Josephson parametric amplifier.

We use a graphene Josephson junction to fabricate a quantum limited amplifier whose bandwidth is electrically tunable.

Polaritons intercations in a monolayer of MoSe₂ .

Due to their peculiar optical properties TMDC show very exciting prospects for the realization of sources of quantum light.

Cathodoluminescence in a van der Waals heterostructure.

Electrons can excite electron-hole pairs in a monolayer of MoS₂ when it is embedded in hexagonal boron nitride.

Towards a spin qubit with holes in Silicon.

The gyromagnetic factor of a confined hole in silicon is anisotropic and electric field dependant. This will allow its coherent manipulation with electric fields.
