a Transfer curve. b Photocurrent (∆Iph) at various gate voltages. c Dependence of R and Iph/Idark on gate voltage. d Dependence of ∆Iph and R on light intensity (850 nm). e EQE spectrum at −30 V gate voltage under illumination of 0.04 mW/cm2. The light intensity is shown in Fig. 5a–c, and Fig. 5e is 0.04 mW/cm2 @ 850 nm. The orange lines with both unfilled and filled circles represent Device #5, and the blue lines with both unfilled and filled squares represent Device #6. The transfer curves of the devices were measured at a constant Vd = −30 V.
