This paper, experiment manufactures device of Metal/Poly-${\gamma}$ Benzyl $_D$-GlutamateOrganic Films/Metal structure using PBDG and I-V properties and C-F properties. The I-V characteristic is measured that approve voltage from 0 to +2[V] of device and the distance between electrode is larger, could know that small current flow and thin film could know that had insulation property. C-F characteristic has each other affinity between the polarization amount and frequency. Permittivity of MIM device could know by dipole that is voluntary polarization of LB film that polarization is happened. The capacitor properties of a thin film is better as the distance between electrodes is smaller.

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. 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, the number of accumulated layers are $3{\sim}9$. Also, we then examined of the MIM device by means of I-V. The I-V characteristic of the device is measured from -3 to +3[V].

We have examined the electrical properties of arachidic acid Langmuir (L) films by using a displacement current measuring technique with pressure stimulation. We give pressure stimulation into organic thin films and detect the Induced displacement current. The structure of manufactured device is Au/arachidic acid/Al, the number of accumulated layers are 17, 19 and 21. Also, we then examined of the MIM device by means of I-V The I-V characteristic of the device is measured from 0 to +1[V]. The insulation property of a thin film is better as the distance between electrodes is larger.

We have fabricated insulating thin films using p-hexadecoxyphenol(p-Hp) that was formed phenol-formaldehyde resin of crosslinked structure from reaction with formaldehyde by LB technique. For fabricated MIM device, the possibility for insulating layers of electronic were investigated by electrical properties of their LB films according to crosslinking of LB films current-voltage (I-V) properties and frequency-capacitance (C-F) characteristics. We have provided evidence for the high insulating performance of phenol-formaldehyde thin films by the LB method. Conductivity of their LB films was as follows: pure water > 1 % aq. Formaldehyde > heat treatment, in the current-voltage (I-V) characteristics. It is demonstrated that insulation properties of crosslinked p-HP LB films were improved. In capacitance-frequency properties, the heat-treated p-HP LB films for crosslinking showed a low relative dielectric constant.

Recently, the study on development of electrical and electronic device is done to get miniature, high degrees of integration and efficiency by using inorganic materials, the study of Langmuir-Boldgett(LB) method that uses organic materials because of the limitation for the ultra small size. In this paper, detected displacement current using PBLG and PBDG, deposition and observed the electrical characteristics to each 1, 3, 5, 7, 9 layers by LB method. Maximum value of change ratio of displacement current by the detected speed and temperature appeared almost lineally, could confirm that it are in comparison relation each other speed-temperature and displacement current. The structure of manufactured device is MIM. Also, we then examined of the MIM device by means of I-V. The I-V characteristic of the device is measured from 0 to +2[V]. The insulation property of a thin film is better as the distance between electrodes is larger.

전기 전자 소자를 제작하는 방법으로 Langmuir-Boldgett(LB)법이 많은 관심을 받고 있다. 수면위에 형성된 단분자막을 압축 또는 확장하면, 분자가 배향하는 과정에서 맥스웰 변위전류(MDC)가 흐른다. MDC는 전속밀도의 변화에 기인해서 흐르므로 MDC를 측정하는 것에 의해 분자의 동적 거동 관찰할 수 있다. 단분자막을 압축하는 속도와 분자면적은 서로 선형적인 관계를 갖고 있다. 본 연구에서는 압축속도를 30, 40, 50mm/min으로 달리하여 단분자막의 동적 거동을 관찰하였으며 LB법을 이용하여 Arachidic acid 단분자를 slide glass 위에 Y-type으로 9$\sim$21층의 다층막을 누적하여 Au/Arachidic acid/Al 소자를 제작하였다. 또한 Metal-Insulator-Metal(MIM) 소자의 I-V 특성을 측정하여 전극간의 거리가 커질수록 절연특성이 좋아짐을 확인하였다.
