A study of the synthetic methods and properties of graphenes
Key Points
- To review diverse synthetic strategies for producing single- and few-layer graphenes and evaluate their resulting surface, electrical, and magnetic characteristics.
- Assessed single-layer graphene production techniques, including micromechanical cleavage, chemical vapor deposition, and the chemical reduction of graphene oxide.
- Examined few-layer graphene synthesis methods, specifically graphite arc discharge and nanodiamond conversion.
- Characterized electrical conductivity, polymer composite performance, field-effect transistor behavior, and magnetic responses across synthesized graphene variants.
- Few-layer graphenes demonstrate concurrent ferromagnetic and antiferromagnetic properties regardless of the synthetic preparation method utilized.
- Ambipolar transport characteristics in field-effect transistor setups occur exclusively in single-layer reduced graphene oxide.
- Charge transport in few-layer graphenes shifts systematically upon surface interaction with electron donor and electron acceptor molecules.
