Hybrid structure of graphene sheets/ZnO nanorods for enhancing electron field emission properties.

Highlights: [•] The ZNRs are synthesized on glass substrates using the hydrothermal process. [•] The graphene films are grown on Cu foils by the thermal chemical vapor deposition technique. [•] The graphene films are transferred onto the ZNRs with various cycles to form the GS/ZNR hybrids by wet transfer process. [•] All GS/ZNR hybrids exhibit higher levels of FE properties than the pristine ZNRs. [Copyright &y& Elsevier]
