A featured "vapor transportation" re-assembly technique was developed to attain layer-by-layer stacking continuous graphene oxide (GO) films on both flat and concavo-concave surface.Few-layer (layer number<10)GO sheets were selectively "evaporated" (carried by water vapor) from the water-dispersed GO suspension and smoothly/uniformly tiled on the substrate surface,with well control on film thickness.A model was proposed for interpreting the re-assembly process.It was found that a current conditioning would induce a reduction of the GO and form an Ohmic contact between the GO-metal interfaces.
