Graphene based field effect transistors: Efforts made towards flexible electronics

• State of art and potentiality of graphene in flexible electronics.
• So far development in the fabrication of graphene based field effect transistors (FETs).
• Compatibility of inorganic, printable and all-graphene active materials with graphene in FETs in flexible format.
• Challenges in graphene based digital applications and its potentiality in high frequency devices.

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.
