  • We investigated transmittance, surface characteristics, and resistivity according to bending of ITO(indium tin oxide) film with four other multi -harrier film). Transmission data of ITO film with four ITO films showed there was about large 90% transmission above 550nm wavelength at three multi-barrier structures. But, both-side hard coated structure showed relatively low 75% transmission above 550nm wavelength. And, surface images measured from SEM (scanning electron microscope) showed both-side hard coated structure have a tendency of more roughness. Also, resistivity change of four other multi-barrier film showed there was the lowest change at one-side hardcoated structure. Subsequently, with result of resistivity change according to position, we knew the resistivity change of the center increased rapidly than that of the edge.

  • Plasma silicon oxynitride film has been applied as a final passivation layer for semiconductor devices, because it has high resistance to humidity and prevents from alkali ion's penetration, and has low film stress. Structure properties of plasma silicon oxynitride film have been studied experimentally by the use of FT-IR, AES, stress gauge and ellipsometry. In this experiment,Si-N bonds increase as NS12TO/(NS12TO+NHS13T) gas ratio increases. Peaks of Si-N bond, Si-H bond and N-H bond were shifted to high wavenumber according to NS12TO/(NS12TO+NHS13T) gas ratio increase. Absorption peaks of Si-H bond were decreased by furnace anneal at 90$0^{\circ}C$. The atomic composition of film represents that oxygen atoms increase as NS12TO/(NS12TO+NHS13T) gas ratio increases, to the contrary, nitrogen atoms decrease.

  • 실험영화작가들은 필연적으로 영화가 가진 물리적인 속성과 한계 그리고 영화만의 단독적인 요소들을 자신들의 영화창작의 핵심으로 간주하였다. 관습적인 영화 규범을 거부하는 태도는 영화의 작동원리에 대한 새로운 관심을 통해서도 강화되었다. 실험영화작가들은 영화의 메커니즘이 어떤 방식으로 영화의 최종 결과물에 영향을 주는지에 대해 질문하였다. 실험영화에서는 극영화의 내러티브에 상응하는 '특정한 전개 구조' 필요하고 이를 위해서 현재의 시점에서 이미지의 흐름에 주목하였다. 움직임의 환영을 만들어 내는 이미지의 연쇄 개념은 다양한 영화적 실험을 가능하게 하였다. 특히, 미국의 구조영화작가들은 이미지들이 연속적으로 움직이는 방식을 변형시킴으로써 관습적인 극영화와는 다른 영화의 의미와 정서를 전달하는 방법들을 모색하였다. 이를 통해서 관습적인 내러티브의 성격과 기능에 대해 문제를 제기하고 새로운 영화전개방식에 대해 탐구하였다. 이러한 구조영화의 전통은 실험영화를 이해하는 핵심적인 개념이며 디지털 영화제작 환경으로 변모하고 있는 오늘날에도 여전히 유용한 접근방식이다.

  • A $TiO_2$ film for photocatalyst was prepared by anodic oxidation at 180V in acidic electrolyte and film formation mechanism was studied. The major part of anodic $TiO_2$ film consisted of anatase type structure and surface morphology exhibited a porous cell structure. The thickness growth rate of the oxide film with anodization time revealed two-stage slope corresponds to the surface morphology between anodic films. The growth of pores on cell structure and the growth rate of film with two-stage slope are related to the constant formation rate of the $TiO_2$ layer.

  • The properties of electroless Ni-B thin film on diamond powder with different parameters (temperature, pH, surfactant etc.) were studied. The surface morphology, structure and composition distribution of the Ni-B film were observed by field effect scanning electron microscope (FE-SEM), energy-dispersive spectrometer (EDS), X-ray diffraction (XRD) and Auger electron spectroscopy (AES). The growth rate of Ni-B film was increased with increase of bath temperature. The B content in Ni-B film was reduced with increase of bath pH. As a result the structure of Ni-B film was changed from amorphous to crystalline structure. The PVP in solution plays multi-functional roles as a dispersant and a stabilizer. The Ni-B film deposited with adding 0.1 mM-PVP was strongly introduced an amorphous structure with higher B content (25 at.%). Also the crystallite size of Ni-B film was reduced from 12.7 nm to 5.4 nm.

  • Electrochemical lithium intercalation into a PECVD (plasma enhanced chemical vapour deposited) carbon film electrode was investigated in 1 M $LiPF_6-EC$ (ethylene carbonate) and DEC (diethyl carbonate) solution during lithium intercalation and deintercalation, by using cyclic voltammetry supplemented with ac-impedance spectroscopy. The size of the graphitic crystallite in the a- and c-axis directions obtained from the carbon film electrode was much smaller than those of the graphite one, indicating less-developed crystalline structure with hydrogen bonded to carbon, from the results of AES (Auger electron spectroscopy), powder XRD (X-ray diffraction) method, and FTIR(Fourier transform infra-red) spectroscopy. It was shown from the cyclic voltammograms and ac-impedance spectra of carbon film electrode that a threshold overpotential was needed to overcome an activation barrier to entrance of lithium into the carbon film electrode, such as the poor crystalline structure of the carbon film electrode showing disordered carbon and the presence of residual hydrogen in its structure. The experimental results were discussed in terms of the effect of host carbon structure on the lithium intercalation capability.

  • Nanophase titania film was obtained by plasma spraying. The structure of titania film was investigated with transmission electron microscopy (TEM). It was found taht the film was composed of grains with mean particle size of 15nm. The crystal structure of nanophase titania film was found to be anatase phase by electron diffraction.

  • Crystal structure and surface morphology of Se thin film fabricated by EBE method had been studied. Se thin film was deposited with amorphous structure until substrate temperature of l00$^{\circ}C$. But Se thin film was grown with monoclinic structure at substrate temperature af over 150$^{\circ}C$, and its lattice constant of a, b and c was 12.76${\AA}$, 9.15${\AA}$ and 10.41${\AA}$ respectively. Also, after heat-treatment at 150。 for 15 min with substrate temperature of l00。, amorphous Se was proved to be hexagonal structure, and its lattice constant of a and c was 4.27${\AA}$ and 4.83${\AA}$ respectively.

  • LDPE pelet is distilled to make 0.5 Wt% solutions and fabricated as LDPE thin film by dropping the solution onto glass substrate, and then annealed the film to be crystalline. The structure is observed as crystalline regions and non-crystalline regions. The crystalline region is exposed at radiation and as the result, there appeared degradation at the total region of the crystal structure. It is considered therefore that radiation exposure at the crystal structure is badly effected on insulation property and lifetime of materials.

  • The effect of pre-existing barrier-type film on porous aluminum oxide film formation during anodization was investigated to control the uniform film growth rate. Initial potential fluctuations during anodization indicated that the breakdown of barrier-film is preceded before the porous formation and the induction time for the porous film growth increases with the increases of pre-existing film thickness. The porous film growth mechanism is lot affected by the presence of barrier film on aluminum surface. In parallel, uniform growth of barrier film underneath the porous structure was attained by two-step anodization processes.
