Graphene based field effect transistors: Efforts made towards flexible electronics

The integration of flexibility in existing electronics has been realized as a key point for practical application of unusual format electronics that can extend the application limit of biomedical equipments and of course daily routine kind of electronic devices. Graphene showed the great potentiality for flexible format owing to its excellent electronic, mechanical and optical properties. Field effect transistor (FET) is a basic unit for digital and analog electronics thus enormous efforts have been attempted to fabricate the flexible FETs in order to get the high performance. This article reviews the recent development of graphene based FETs including the fabrication and active layers material compatibility in flexible format. (C) 2013 Elsevier Ltd. All rights reserved.
