Graphene for Electron Devices: The Panorama of a Decade

Abstract

Graphene emerged in 2004 as the first 2-D material with exotic properties. Since then the literature has been flooded with reports, with physicists, material scientists, and engineers grabbing their respective shares. Numerous reviews have also been published. While these reviews have done excellent works in their own ways, new reports are coming up faster than they could draw the attentions of researchers. The authors, therefore, feel that there is a demanding scope for a fresh review. Further, many aspects of graphene are not covered in the reviews so far. New concept devices are also entering into the arena of graphene day by day. The purpose of this paper is therefore to present a comprehensive review on the conventional as well as novel device applications of graphene. While we believe that graphene is the material which will transform the electron devices from the classical regime to the quantum world, it is difficult to believe that it will be a complete substitute to silicon in the near future.
