  • The morphology variat~on of diamond thin films, grown by microwave plasma chem~cal vapor deposition, was investigated. With increasing substrate temperature from $550^{\circ}C$ to $750^{\circ}C$, the film morphology was changed from {111} to {100}, and then to cauliflower. The nondiamond components in the film increased with increasing temperature. Micro Raman spectrum suggested that the nondiamond components might exist along the boundaries of d~amond particles. The texture of diamond films, analyzed by X-ray diffraction, was varied from random orientation to <100> , and finally to <110> with increasing substrate temperature.

  • The purpose of this study was to examine university students' clothing and cosmetics purchasing behaviors according to gender and major. For the study, 337 university students living in Chonbuk area participated in this survey research. The data were analyzed utilizing SPSS statistics package. Exploratory factor analysis, reliability test, and t-test were used. Five factors in each clothing and cosmetics purchasing orientation were generated from the factor analysis. According to gender and major, clothing and cosmetics purchasing behavior were significantly different. Female students showed more impulsive, rational, and economical purchasing orientations than male students did. On the contrary, male students showed more independent and convenient purchasing orientations. The students with fashion design major showed higher tendency in impulsive and rational clothing purchasing orientations than non-fashion design major students. Finally, clothing and cosmetics purchasing behaviors were significantly different by gender and major in terms of information usage and expenditure for clothing and cosmetics.

  • There arc several important issues in AC PDP researches such as cost reduction, reliability, and good image quality. The properties of MgO layer is thought to be one of the most important (actors that affects the panel reliability through the firing voltage variation. The MgO thin film mainly has (111), (200) and (220) crystal orientation. It is reported that (111)-oriented film helps decreasing the discharge voltage, and (200)-oriented film improves the misfiring on high temperature and the image sticking. In this study, we investigated the relations between the crystal orientation and e-beam evaporation process parameters such asdeposition rate, temperature of substrate, and distance between the target(MgO tablet) and the substrate.

  • TiN (titanium nitride) films were prepared using the RF magnetron sputtering technique. The films were deposited by pure $N_2$ plasma sputtering. Their mechanical properties, such as nano-indentation hardness, friction coefficient, and surface wettability, have been investigated. X-ray diffraction (XRD) studies revealed that the orientation of $TiN_X$ films changed towards the (111) orientation with decreasing working pressure due to a strong compressive stress during deposition. The strongest TiN (111) orientation was found when the film was deposited at a working pressure of 1 Pa. This film showed the largest hardness (16 GPa) and smallest friction coefficient (0.17) among the studied samples. Moreover, this film was found to be accompanied by a water-repellent surface with water contact angle more than $100^{\circ}$.

  • TiN films were deposited onto Stellite 6B alloy (Co base) by the reactive magnetron sputter ion plating. As the bias increases, TiN film changes from columnar structure to dense structure with great hardness and smooth surface due to densification and resputtering by ion bombardment. The content of oxygen and carbon impurities in the TiN film decreases greatly when the substrate bias is applied. The preferred orientation of the TiN films changes from (200) to (111) with decreasing $N_2$/Ar ratio, and from (200) to (111) and then (220) with increasing the substrate bias. The change of the preferred orientation is discussed in terms of surface energy and strain energy which are related to the impurity contents and the ion bombardment damage. The hardness of the TiN film increases with increasing compressive stress generated in the film by virtue of ion bombardment. It becomes as high as up to 3500kgf/mm$^2$ when an appropriate substrate bias is applied.

  • In this study the initial stage nucleation and growth of Ni silicide on (001) Si by evaporation and furnace annealing have been investigated by transmission electron microscopy. The pressure was $10^{-6}$ Torr during evaporation and annealing. And the annealing temperature to produce $NiSi_2\;was\;800^{\circ}C$. From the evaporated film, $NiSi_2$ nucleus has grown into Si substrate with an epitaxial orientation relationship. Interfaces between $NiSi_2$ and Si were A-type {111} interfaces and {100} $NiSi_2$ interfaces were also observed at the initial stage of nucleation. Ni silicide grew into Si substrate, but the nucleus partly grew into the evaporated film, with no facets, from the nuclei in the Si substrate. $NiSi_2$ nucleus with (111) habit planes was also observed.

  • The effect of Ni content in Cu underlayer on the magnetoresistance of Cu/Co artificial superlattice has been investigated. As the content of Ni increased, the preferred orientation of artificial superlattice changed from fec (100) to fcc (111) due to the change of the preferred orientation of the underlayer. When the content of Ni was 6 %, 26.7 % of magnetoresistance with 175 Oe of saturation field could be obtained in ${[Cu(19\AA)/Co(30\AA)]}_{20}|Cu-6%Ni(200\AA)/Si$.

  • The effects of pulse current parameters on the composition and the microstructure of Pd-Ni alloy electrodeposits were studied. The cathode current efficiency of p.c. electrolysis conditions decreased with increasing both mean and peak current density and was lower than those under D.C. electrolysis condition. Palladium content of Pd-Ni alloy increased with increasing both peak current density and on-time, while it decreased with increasing mean current density and duty cycle. The preferred orientation of Pd-Ni alloys changed with increasing mean current density in the sequence of (111)+(110).(100) or (110)longrightarrow(111)longrightarrow(100) or random distribution of crystal structure. The surface morphology of Pd-Ni alloy changed mainly according to the mean current density and was related to the preferred orientation.
