1) Electronic properties, vibrational states and applications of 2D materials and devices. (group page)

- Electronic phase transitions, vibrational states. These are directly related to the density of electronic states at the Fermi level, the strength of the electron-phonon coupling as also to the number of layers of 2D material. We control the density of states at the Fermi level through our space charge doping method. Vibrational and electronic properties also depend on the number of 2D layers.

- Efficient optoelectronic devices. Combining layers of 2D materials with complementary properties is a promising method to form a hybrid structure with new properties. An example is combining graphene (well suited for charge transport) with a layered direct gap semiconductor (ideal for light to charge conversion), for an efficient photoconductor. Such a device can also be configured in a vertical geometry to maximize device effective volume and minimize losses in transport.

2) Electronic and structural properties of materials using X-ray synchrotron spectroscopy. I have used and developed methods for measurements of electronic momentum distributions, electronic excitations and phonons in solids, at the European Synchrotron Radiation Facility at Grenoble and at the UPMC. I co-proposed the GALAXIES inelastic scattering beamline at SOLEIL, Saclay. Some areas I have focused on include:

    Zoom Science - Phonons dans la glace VII et VIII : courbes de dispersion et désordre hydrogène

    Les glaces VII et VIII sont les phases dominantes de l’eau solide car elles sont stables sur une énorme plage de pression, entre 2 et 50 GPa, et il n’est pas improbable qu’on les trouve à l’intérieur de quelques exoplanètes. En collaboration avec le CEA et l’ESRF, les chercheurs de l’IMPMC ont déterminé...
