ABSTRACT

Carbon nanotube (CNT) and graphene nanoribbon (GNR) are two new important carbon nanomaterials in the nanometer regime. Though CNT was discovered more than two decades ago, in 1991, by Japanese physicist Sumio Iijima, GNR was discovered more recently, in 2004, by Andre Geim and Konstantin Novoselov at the University of Manchester. Since their discovery, both of these carbon nanomaterials have gained a lot of importance due to their remarkable properties. Significant progress has been made in finding out the fundamental properties, exploring the possibility of engineering applications, and growth technologies. This chapter provides a brief description about CNT and GNR.
