    • We cannot completely exclude the existence of P3HT structural difference near by the interface between the semiconductor and insulator in the device, which may not be detected by means of ordinary XRD and UV-vis measurements. As carrier transport generally occurs at the interface between semiconductor and insulator, even a slight structural change will significantly influence the electrical characteristics. The structural difference may be a density of crystalline domains at the interface: when the structure of majority domains is suitable for carrier transport, the device will give high mobility

    • The estimated trap density values are small compared with those reported by others [22,23]. This result indicates that our substrate cleaning and SAM treatment are adequate.
