Figure 2

(a) The AFM image of the P(VDF-TrFE-CTFE) film without UVO treatment (2 μm × 2 μm). (b) XRD patterns of the P(VDF-TrFE-CTFE) films with or without UVO treatment. (c) The AFM image of the pentacene film deposited on the P(VDF-TrFE-CTFE) film without UVO treatment (5 μm × 5 μm). (d) Polarization-electric field hysteresis properties for ITO/P(VDF-TrFE-CTFE)/Au ferroelectric capacitors. (e) The I–V characteristics of the P(VDF-TrFE-CTFE) films with or without UVO treatment. (f) The linear transfer characteristics of the FE-OFET based on the P(VDF-TrFE-CTFE) film without UVO treatment. The inset of (a) shows the water contact angle on the P(VDF-TrFE-CTFE) film without UVO treatment. The inset of (c) shows the morphological profile of the blue lined region in the image.
