抄録

New ultrathin film devices, i. e. a memory and/or a sensor, are proposed using microscopic behavior of organic molecules, i. e. a polarization phenomenon of dipoles. The devices are fabricated from organic ultrathin films with sandwich electrodes, containing dipoles with various relaxation times, or dipoles that change with some stimulation : irradiations of the light, chemical treatments and so on. The polarizations of the dipoles in the devices are odulated by optional and multiple writing signal patterns, i. e. voltage-time patterns, during the decrease of a triangular thermal pulse, and the patterns are detected as depolarization currents during the increase of the pulse. The writing and the detecting signals are simulated for the memory device. Furthermore, the fundamental properties are examined for phosphatidic acid LB film devices and for spiropyran LB film devices.
