Hybrid Graphene Devices for Opto(electro)Mechanics

Département Nanosciences, Groupe Systèmes hybrides de basse dimensionalité
Institut Néel, CNRS-Grenoble, FRANCE

Graphene appears as a very promising material to implement on a same platform, novel type of devices presenting at the same time tunable electronic, mechanical and optical properties.

I will present recent results in our group involving freestanding hybrid graphene devices forming optical Fabry-Perot cavities. Combination of spatially resolved and confocal measurements of elastic and inelastic scattering of a light probe offer new ways to probe mechanical and thermal effects. Among different applications, I will show that a purely spectral detection of mechanical resonance together with the enhanced detection of molecular species can be achieved. Electromechanical effects will also be presented together with the influence of decoration of graphene by metal clusters to induce new states within graphene such as global superconducting state.
