Carbon nanotubes and graphene form a class of nanoscale objects with exceptional electrical, mechanical and structural properties. I propose to exploit these unique properties to fabricate and study various nanoelectromechanical systems (NEMS) based on graphene and nanotubes. Specifically, I will address two directions with major scientific interests:
1- I propose to study electromechanical resonators based on an individual nanotube or on a single layer of graphene. My group has a leading position in this recent research field and the idea is to take advantage of our expertise for two sets of experiments, one on inertial mass sensing and one on the exploration of quantum motion. These two topics are generating at present an intense activity in the NEMS community. Experiments are usually carried out using microfabricated silicon resonators but the ultra low mass of nanotubes and graphene has here an enormous asset. It drastically improves the sensitivity of mass sensing and it dramatically enhances the amplitude of the motion in the quantum regime.
2- My team will fabricate and exploit nanomotors based on nanotube and graphene. Only few man-made nanomotors have been demonstrated so far. Reasons are multiple. For instance, the fabrication of nanomotors is technically challenging. In addition, friction forces are often so strong that they hinder motion. Because of their unique properties, nanotubes and graphene represent a material of choice for the development of new nanomotors. We will construct nanomotors with different layouts and address how electrical, thermal or chemical energy can be transformed into mechanical energy in order to drive motion at the nanoscale.
