Photocurrents and band diagram of the fabricated devices. Photocurrents of devices with three different SWNT concentrations as a function of applied X-ray dose rate under the reverse bias voltages of (a) 60 V, (b) 90 V, and (c) 120 V. Insets show the devices' time-dependent responses. (d) Band diagram of the flexible X-ray detector. Charges can be easily injected into the active layer through the reduced Schottky barrier between the active layer and electrodes.
