An improved synthesis route to graphene for molecular sensor applications

This article presents an improved graphene oxide synthesis method and its subsequent simple reduction technique with hydrazine vapour more efficiently to produce large area graphene flakes with a dramatic change in average sheet resistance of ∼145 kΩ/□ as compared to existing annealing methods. With...

Description
Summary:This article presents an improved graphene oxide synthesis method and its subsequent simple reduction technique with hydrazine vapour more efficiently to produce large area graphene flakes with a dramatic change in average sheet resistance of ∼145 kΩ/□ as compared to existing annealing methods. With the above characteristics, a high-performance and low-voltage operating graphene field-effect transistor (FET) was achieved with the potential to be used as detection platform for biomolecules.
