(a) Demonstration of VOPO4/graphene hybrid thin film on the surface of PET substrate, exhibiting transparent feature. (b) The cross-section SEM image of the hybrid thin film with the thickness of ~ 90 nm. The surface of the hybrid film, of which the graphene lies under the VOPO4 layers as indicated by the white arrows, is shown in the inset. Scale bar, 500 nm; Inset scale bar, 100 nm. (c) The Raman spectra of graphene film (brown line), VOPO4 film (red line) and VOPO4/graphene hybrid film (blue line), respectively. (d) The temperature dependence of planar resistivity of the VOPO4/graphene hybrid film and pure VOPO4 nanosheet thin film, where the incorporation of graphene greatly enhanced the electrical conductivity in the VOPO4/graphene hybrid film.
