Overview

The 2D spintronics team is developing the large area growth of 2D materials by molecular beam epitaxy (MBE). Our aim is to study fundamental magnetic and spin transport properties of 2D transition metal dichalcogenides down to the monolayer limit or in van der Waals heterostructures. The main research topics are two-dimensional magnetism, spin-charge interconversion phenomena, magnetic doping and the integration of 2D materials in devices. The strength of the team relies on its long experience in the physics of 2D materials and on a unique (in France and Europe) MBE platform to grow 2D materials and vdW heterostructures on large area.

Research topics

2D magnets

MBE growth of 2D ferromagnets and fundamental study of two-dimensional magnetism: effects of low-dimensionality (down to one monolayer) and low symmetries, manipulation by electric field and strain, proximity effects, topological effects, new spin textures (ex. skyrmions).

Spin-charge interconversion

Fundamental study of spin-charge interconversion phenomena in 2D materials and van der Waals heterostructures using spin pumping, THz spintronic emission and spin-orbit torques.

Magnetic doping

Development of magnetic and electrical doping to synthesize 2D diluted magnetic semiconductors (DMS) or to reach electronic bands with specific spin texture.

2D material integration

Integration of 2D materials in RF transistors, RF switches and memristors. Optimization of carrier mobility and electrical switching processes.
