Pentacene Thin-Film Transistors with Hydrophobic Nanostructures on a Polymeric Gate Insulator : Figure 1

Figure 1: AFM image of the nanostructured cPVPinsulator(20 μm × 20μm): the inset shows the AFM image of the bare cPVP surface. The side views of sessile drops on (b) the bare cPVP layer and (c) the nanostructuredcPVP layer, respectively.
