title: Electrical property of organic thin films for power device.
abstract: Monolayers of lipid on a water surface have attracted much interest as models of biological membranes, but also as precursors of multilayer systems promising many technical applications. Until now, many methodologies have been developed in order to gain a better understanding of the relationship between the structure and function of the monolayers. Maxwell displacement current (MDC) measurement has been employed to study the dielectric property of Langmuir-films. MDC flowing across monolayers is analyzed using a rod-like molecular model. A linear relationship between the monolayer compression speed alpha and the molecular area A(m). Compression speed alpha was about 30, 40, 50 mm/min. Langmuir-Blodgett (LB) layers of Arachidic acid deposited by LB method were deposited onto slide glass as Y-type film. The structure of manufactured device is Au/Arachidic acid/Al (MIM), the number of accumulated layers are 9-21. Also, we then examined of the Metal-Insulator-Metal (MIM) device by means of I-V. I-V characteristics of the device are measured from -3 to +3 [V]. The insulation property of a thin film is better as the distance between electrodes is larger.
