Figure 4

The linear transfer characteristics of the FE-OFETs based on the P(VDF-TrFE-CTFE) dielectric modified by UVO treatment for (a) 15, (b) 30 and (c) 60 min, respectively, measured at different VG sweeping ranges. (d) The evolution of the mobility and the memory on/off ratio of the FE-OFETs with the time of UVO treatment on the P(VDF-TrFE-CTFE).
