A photoresponsive transistor by MA-DPN. a, Illustration of the deposition of the C60-PEG ink between electrodes by MA-DPN. b, AFM topographical image of the photoresponsive transistor. The four electrodes are connected by two perpendicular lines of the C60-PEG ink. c, The I–V curve of the transistor in the dark (black trace) and under white light from a 50 W tungsten-halogen lamp (red trace).
