Abstract
A significant enhancement of photoresponse from the light-controlled conductive switching based on nanocomposites was experimentally demonstrated. nanocomposites were synthesized via a facile wet-reduced method. The crystalline structure, morphologies, and photoluminescence of the nanocomposites were characterized and analyzed. The fabricated conductive switching was measured under the irradiation of a continuous laser. When the laser was turned on and off alternately, the photoconductive switching obviously displayed a state conversion between “on” and “off” reversibly. Furthermore, the typical current–voltage (I–V) and current–time (I–t) curves exhibited a relatively high switching ratio () of 3.25 and a fast response time of 0.45 s. The excellent “on–off” characteristics of the device show promising applications in memory storage and logic circuits.
