Electrical Characteristics of Maleate Copolymer LB Films

Langmuir-Blodgett (LB) method have been used by many rescarcher because of its facility to control the thickness of film as molecular order and orientation of molecular. We fabricated MIM device using copolymer LB films of $2C_{18}MA-VE_2$ and elecctrical conduction mechanism in ultra-thin LB film were investigated. In our experimental results, the maleate copolymer LB film have the properity of insulator like organic ultra-thin fiim. Its diclcctric constant was about 3.5 and its voltage generation about 0.1 Volt. And Schottky current was apeared as electrical conduction current and Schottky barrier was about 0.9(eV).
