Thème : Propriétés intrinsèques des nanotubes individuels et du graphène

Our main objective is to study individual isolated carbon nanostructures in order to address their intrinsic properties. Our overall approach involves the combined use of powerful characterization tools with diagnostics of the nanostructure physical properties. Our team capability covers many aspects involved in individual nanotube investigations. We are using a broad set of experimental techniques adapted for investigations at the single nano-object level : micro-Raman and optical spectroscopy, scanning probe microscopy, electrical and opto-electrical transport measurements. Our projects interface the expertises of our team on : (a) sample preparation and electronic device fabrication (CVD synthesis, individual nanotube suspension processing and microfabrication techniques), (b) the precise characterization and metrology of isolated carbon nanostructures (c) the ability to carry out original measurements of the physical properties on individual nanostructures.

Our interests are mainly related to the investigation of individual single-walled carbon nanotubes but we are also researches on other nano-systems like grapheme or double-walled carbon nanotubes. We have developed several collaborations in various fields such as transmission electron microscopy, optical spectroscopy, chemistry, theory and simulation...

Camassel (GES, Montpellier) Graphene is a two-dimensional honeycomb lattice of carbon atoms. With carbon nanotubes, graphene is another promising nanomaterial for a carbon-based nano-electronic. Since graphene is uniquely composed of surface atoms, its physical properties are drastically affected by the environment. Part of the (...)
