Sensors: A Quasi-Liquid Iontronic–Electronic Light-Harvesting Hybrid Photodetector with Giant Response (Adv. Mater. 27/2012)



original image

The image depicts a novel device architecture composed of ZnO nanorods with surface-dispensed agarose-gel as a quasiliquid iontronic-electronic light-harvesting hybrid photodetector. On page 3686, S. Ogale and co-workers show that this configuration exhibits a three orders of magnitude stronger photoresponse and a shorter response time as compared to the bare ZnO nanorod-based device. Moreover, this response has an extended tail in the visible region.
