  Description

Significant progress and novel discoveries have been made in the past two decades in the science of nanometer scale carbon based materials. Novel physical phenomena characterizing low dimensional systems have been discovered leading to the development of prototype devices. Graphene nanoribbons have very recently emerged at the front of this field due to their unique electronic, magnetic and mechanical properties and the ability to fabricate them in a controllable and reproducible manner. Despite the considerable progress that has been made in the controlled fabrication and the understanding of the physical properties of graphene nanoribbons, currently, much less is known regarding their chemical nature. The large surface to volume ratio and the existence of reactive edges are expected to considerably enhance their chemical reactivity with respect to related systems such as carbon nanotubes and infinite graphene surfaces. Thus, understanding the surface and edge chemistry of graphene nanoribbons and utilizing it for chemical sensing purposes is a major challenge. It is the purpose of this research program to address this challenge. To this end, our proposed program will focus on the development and implementation of a new model that will allow the accurate treatment of the electronic and transport properties of finite extended systems such as graphene nanoribbon surfaces. Using this model we will study in depth the process of molecular adsorption on the surface and edges of nanoribbons and its influence on the electronic properties of the ribbon. Furthermore, we propose to study new schemes to control the reactivity of the ribbon and the selectivity of the adsorption process. We believe that the proposed research program will enhance the understanding of the chemical nature of graphene nanoribbons and will provide guidelines for the design and fabrication of novel nanoscale sensing devices.
