摘要：

Large photocurrent multiplication reaching 10000 times has been observed in a perylene pigment film sandwiched between Au electrodes. The phenomenon occurs at the interface between the perylene film and a negatively biased Au electrode and is found to be associated with electron injection from the Au electrode to the perylene film through the depletion layer formed in the pigment film under a high electric field, which is built up by the photoaccumulated space charges of trapped holes near the interface.
