Graphene is the building block of graphitic materials such as fullerenes, carbon nanotubes and graphite. It is a semi-metal made of sp2 hybridized carbon atoms packed in a hexagonal lattice. This two-dimensional material exhibits outstanding physical properties, which hold great promise for applications in spintronic, electro-mechanical, and opto-electronic devices. Several multidisciplinary research directions are currently pursued in our team.
We are particularly interested in the spin filtering properties of graphene/ferromagnet hybridized interfaces and their integration into vertical magnetic tunneling barriers, as well as in the study of spin diffusion processes in lateral graphene spinvalves. “Resist free” methods for the large scale production of graphene transistors are also developed for applications involving molecules or delicate substrates in contact with the graphene layers. We also actively investigate the optical, opto-electronic and mechanical properties of pristine freestanding graphene by means of micro-Raman spectroscopy. Finally, in the context of opto-electronic applications, we are exploring the interaction between graphene and individual semiconductor nanostructures.
