Graphene-Based Devices for Beyond CMOS Applications

Graphene, a single-layer thick atomic planner sheet with densely packed honeycomb crystal lattice having excellent electronic, optoelectronic and mechanical properties is grabbing worldwide market in the area of electronics, home appliances and medical field. The present book chapter emphasizes on graphene-based field effect transistor devices towards different applications. It comprehensively reviewed the synthesis of graphene, properties of graphene and fabrication of graphene nanostructure (nanowire, nanoribbons)-based devices. Mostly, single and bilayer graphene-based field effect transistor structures have been discussed with special emphasis on logic and radio frequency applications. Further, use of graphene transistor for switching and electronics applications have been taken into consideration to prove the potentiality of the material. Challenges for synthesis of graphene with difficulties to fabricate field effect devices towards different application and their probable potential solution to mitigate the issues for future opportunities have been illustrated.
