  • This paper presents direct ${\mu}c$-Si:H thin film growth on the glass substrates using RPCVD system (remote plasma chemical vapor deposition) in low temperature. Hydrogenated micro-crystalline silicon deposited by RPCVD system in low temperature is very useful material for photovoltaic devices, sensor applications, and TFTs (thin film transistors). Varying the deposition conditions such as substrate temperature, gas flow rate, reactive gas ratio $(SiH_4/H_2)$, total chamber pressure, and rf power, we deposited ${\mu}c$-Si:H thin films on the glass substrates (Corning glass 1737). And then we measured the structural and electrical properties of the films.

  • The effect of Na on the structural and electrical properties of CIGS films were studied and their effects on the CIGS/Mo thin film solar cells were investigated. Soda-lime glass and Corning glass were used as substrates to compare the effect of Na diffusion into CIGS film. The resistivity of CIGS films was not changed in the Cu-poor region due to diffusion of Na from soda-lime glass but was mainly determined by the surface resitivity controlled by excess Na.

  • ITO(Indium Tin Oxide)는 전도도와 투과도 특성이 뛰어나 디스플레이, 태양전지, LED 등 여러 산업에서 전극 물질로 널리 사용 되어져 왔다. 최근 ITO의 사용이 급격히 증가하면서 이에 대한 연구가 활발히 진행되고 있다. ITO는 막의 특성을 좋게 하기 위하여 증착 시 Ar gas와 함께 $O_2$가스를 첨가하기도 한다. 본 연구에서는 산소 분압에 따른 ITO 박막의 전기적, 광학적 특성에 대하여 연구하였다. Corning사의 eagle 2000 glass 기판위에 스퍼터링을 이용하여 ITO layer를 증측하였고, 증착시, $O_2$ partial pressure를 0 - 0.5%까지 0.1% 간격으로 가변하였다. 증착된 샘플은 Sinton사의 UV-vis 장비를 이용하여 광학적 특성을 측정하였고, Hall measurement 장비를 이용하여 전기적 특성을 측정하였다. ITO 박막은 $O_2$의 partial pressure가 증가할수록 향상된 전기적, 광학적 특성을 나타내었다.

  • Submicron gratings are fabricated holographically on thin film single mode and multimode waveguides. Thin film waveguides are made by spin-coating polyurethane solution on the substrates of microscope slide glass and Corning 7059 glass. In order to characterize thin film waveguides, the refract사e index and the thickness of thin films are measured by using the m-line spectroscopy. The fabricated gratings are tested as a grating coupler, a mode converter, and a beam splitter. Also chirped gratings are fabricated to observe beam expansion phenomena and thus the possibility of the wavelength demultiplexing.

  • Sb-doped SnO2 films were formed on Corning glass 7059 substrate by chemical vapor deposition using simulataneous hydrolysis of SnCl4 and SbCl5. Fairly good transparent conducting film with a low resistivity of ~6$\times$10-4{{{{ OMEGA }}cm and high average optical transparency above ~85% in the range of visible light was obtained at the deposition condition of 50$0^{\circ}C$ and input-gas ratio, [Psbcl5/Psncl4] of 0.05. Film conductivity was improved without loosing optical transparency at light doping of Sb and found to be due to the increase of electron concentration. However, high doping of Sb into SnO2 film largely deteriorated conductivity, optical transparency and crystallinity of the film.

  • The purpose of this study Is to research the clothing and textiles recorded in Heikemonokatary which was written from 1131 to 1198. The research materials are 36 kinds of men's clothes and ornaments, 6 kinds of women's things, 10 kinds of colorings and 6 kinds of textiles. The results of this study are as follow : 1. There were many advanced warriors' clothes. Especially the helmets and armors were very gorgeous. The shapes of warriors' knives, arrows, shields were concretely described. The women's clothes were mostly unchanged from Nara period and Heian period. Women wore clothes on their heads when they went out. 2. One particular thing in color is that the brown color of that period was navy blue which is symbolic of victory. There were some textiles which was woven with the boiled silk thread in the latitude and the raw silk thread in the longitude. Besides, the blackening of teeth, the bobbed haler of boys, and the celebration of one's corning of age were described in the book.

  • Low RF power density was used for preparing transparent conducting AI-doped ZnO (AZO) thin films by RF Magnetron Sputtering on Corning 1737 glass. The dependence of films' structural, optical and electrical properties on sputtering gas, film's thickness and substrate temperature were investigated. Low percent of incorporated H2 in Ar sputtering gas has proven to reduce film's resistivity and sheet resistance as low as $4.1\times10^{-3}{\Omega}.cm$. It also formed new preferred peaks orientation of (101) and (100) which indicated that the c-axis of AZO films was parallel to the substrate. From UN-VIS-NIR Spectrophotometer analysis, it further showed high optical transmittance at about $\~ 90\%$ at visible light spectra (400-700nm).

  • The post-annealing treatments on rf magnetron sputtered PZT($Pb_{1.05}(Zr_{0.52},\;Ti_{0.48})O_3$) thin films($4000{\AA}$) have been investigated for a structure of PZT/Pt/Ti/Coming glass(1737). Crystallization properties of PZT films were strongly dependent on RTA(Rapid Thermal Annealing) annealing temperature and time. We were able to obtain a perovskite structure of PZT at $650^{\circ}C$ and 10min. P-E curves of Pd/PZT/Pt capacitor demonstrate typical hysteresis loops. The measured values of $P_r$, $E_c$ were $8.1[{\mu}C/cm^2]$, 95[kV/cm] respectively. Polarization value decrease about 25% after $10^9$ cycles.

  • We deposited $SnO_2$:F thin films by atomospheric pressure chemical vapor deposition(APCVD) on corning glass. $SnO_2$:F films were used as transparent conductive oxide (TCO) electrode for Si thin film solar cells. We have investigated structural, electrical and optical properties of $SnO_2$:F thin films and fabricated thin film Si solar cells by plasma enhanced CVD(PECVD) on $SnO_2$:F thin films The cells were characterized by I-V measurement using AM1.5 spectra. Conversion efficiency of our cells were between 5.61% and 6.45%.
