Detection of Electron Transfer in Multilayer Systems by a Displacement Current-Measuring Technique

A displacement current-measuring technique was used for the detection of transportation of photoexcited electrons at the interface between electrodes and monolayers prepared on the electrodes. Displacement current was found to be generated by the motion of electrons at the interface. The current-measuring technique was also used for the detection of transportation of photoexcited electrons between two adjacent single monolayers. Displacement current was found to be generated in the direction predicted by the motion of electrons.
