Current-voltage characteristics and photocurrents of the fabricated devices. (a) Dark current-voltage characteristics of flexible X-ray detectors with various SWNT concentrations. Ambipolar characteristics were observed as SWNT concentration was increased. (b) Photocurrents as a function of applied reverse bias voltage for devices with different SWNT concentrations. Photocurrent was enhanced with increasing SWNT concentration up to 10.67 nA at 150 V for the 0.010 wt.% SWNT device.
