Carbon-based Nanosciences & Nanotechnologies: Nanotubes and Graphene at the Heart

Stephan Roche

CEA, Institut of Nanosciences and Cryogenics

In the early nineties, the development of high-precision nano-characterization tools (such as high resolution TEM, STM...) has enabled the discovery and the study of carbon nanotubes [1]. For now almost two decades, such nano-material has been used as a playground for the exploration of Nanosciences and the understanding of physical phenomena in low dimension [2]. The recent fabrication of two-dimensional graphene has sparked novel interest in carbon-based nanoelectronics, together with excitement in novel transport properties conveyed by sp2 hybridization and massless Dirac Fermions physics [3].
In this talk, I will draw some historical perspective on nanotubes and graphene discoveries, including current scientific and technological challenges. Of particular concern are the physical properties of chemically-modified forms of carbon nanotubes and graphene based materials, owing to their related potentiality for new material and device functionalities, covering the so-called beyond-CMOS fields of application.
