Abstract

In this study, in order to confirm the application possibility to the molecular electronic device, morphlogical property of the Arachidic acid was investigated. We have investigated morphology by BAM image and AFM. ${\pi}$-A curves investigated surface pressure of this LB film from liquid to solid state ranged between 40 to 45 mN/m. BAM images investigated the different states of Arachidic Acid LB film. When the surface pressure reaches at 40 mN/m, the monolayer was deposited onto the hydrophilic glass substrates by Y-type deposition. We also investigated the frequency characteristics of LB modified glass by QCM. We investigated morphology of arachidic acid by AFM. As a result, we obtained the frequency characteristic and morphology of LB films from controlling the deposited layers.
