摘要：
We examined the photoresponse of the surface potential across polyimide (PI) Langmuir-Blodgett (LB) films deposited on bas-Au electrodes, and then analyzed the surface potential change initiated with photoirradiation by assuming a model based on the three-step process of photoconductivity in polymers. In the model, photogeneration of carriers is of the Onsager type, where a space charge field formed at the PI/base-Au electrode interface makes a significant contribution to the photogeneration, and the succeeding carrier transport does not suffer from bimolecular recombination.
