Abstract

We investigated electric and dielectric properties of metal/insulator/metal (MIM) device using maleate copolymer LB films. The thickness of maleate copolymer LB film measured by ellipsometry and X-ray diffraction was about 27-30[/spl Aring/]. The maleate copolymer LB films have the property of insulators such as organic ultra-thin films. The electrical conduction mechanism was Schottky current determined by the measurement of current-voltage characteristics, and its conductivity was 10/sup -14/-10/sup -15/ [S/cm]. Dielectric constant was about 5.0-6.0 using various measurement methods: I-V and frequency-dependent dielectric properties. Schottky barrier was about 0.9-1.0[eV]. The activation energy was 0.74 [eV] from the measurement of current-temperature characteristics. The frequency-dependent dielectric properties involved orientational polarization by the dipole.
