Electrostatic interfacial phenomena and I-V characteristics of Au/polyimide Langmuir-Blodgett film/Al element

In this paper, we have analyzed the I-V characteristic of metal (Au)-PI LB film-metal (Al) elements, taking into account the interfacial electrostatic phenomena and the existence of the interfacial electric states at the metal/PI LB film interfaces. A modification of the potential barrier height in the Richardson-Schottky model has been made. It is demonstrated that the interfacial electronic states play an important role in determining the I-V characteristic of the Au-PI LB film-Al structure.
