We examined the characteristics of indium tin zinc oxide (ITZO) thin film transistors (TFTs) on polyimide (PI) substrates for next-generation flexible display application. In this study, the ITZO TFT was fabricated and analyzed with a SiOx/ SiNx gate insulator deposited using plasma enhanced chemical vapor deposition (PECVD) below 350℃. X-ray photoelectron spectroscopy (XPS) and secondary ion mass spectroscopy (SIMS) results revealed that the oxygen vacancies and impurities such as H, OH and H2O increased at ITZO/gate insulator interface. Our study suggests that the hydrogen related impurities existing in the PI and gate insulator were diffused into the channel during the fabrication process. We demonstrate that these impurities and oxygen vacancies in the ITZO channel/gate insulator may cause degradation of the electrical characteristics and bias stability. Therefore, in order to realize high performance oxide TFTs for flexible displays, it is necessary to develop a buffer layer (e.g., Al2O3) that can sufficiently prevent the diffusion of impurities into the channel.

Aluminum-oxide(Al2O3) thin films were deposited by electron cyclotron resonance plasma-enhanced atomic layer deposition at room temperature using trimethylaluminum(TMA) as the Al source and O2 plasma as the oxidant. In order to compare our results with those obtained using the conventional thermal ALD method, Al2O3 films were also deposited with TMA and H2O as reactants at 280 oC. The chemical composition and microstructure of the as-deposited Al2O3 films were characterized by X-ray diffraction(XRD), X-ray photo-electric spectroscopy(XPS), atomic force microscopy(AFM) and transmission electron microscopy(TEM). Optical properties of the Al2O3 films were characterized using UV-vis and ellipsometry measurements. Electrical properties were characterized by capacitance-frequency and current-voltage measurements. Using the ECR method, a growth rate of 0.18 nm/cycle was achieved, which is much higher than the growth rate of 0.14 nm/cycle obtained using thermal ALD. Excellent dielectric and insulating properties were demonstrated for both Al2O3 films.

The properties of zinc oxynitride semiconductors and their associated thin film transistors are studied. Reactively sputtered zinc oxynitride films exhibit n-type conduction, and nitrogen-rich compositions result in relatively high electron mobility. Nitrogen vacancies are anticipated to act as shallow electron donors, as their calculated formation energy is lowest among the possible types of point defects. The carrier density can be reduced by substituting zinc with metals such as gallium or aluminum, which form stronger bonds with nitrogen than zinc does. The electrical properties of gallium-doped zinc oxynitride thin films and their respective devices demonstrate the carrier suppression effect accordingly.

As a result of analysis of Jangaji used to jangheung oak-mushroom, water content appeared to young oakmushroom 83.13%, completely mature oak-mushroom 66.82%. As the harvest times are delay, water content decreased. As a oak-mushroom was mature, crude protein content increased. But it was decreased after completely maturing. The crude fat content in the pileus part 10-20 times were higher than a stalk parts. As a oak-mushroom grew, content of crude fiber increased in both a pileus and a stalk. The reducing sugar content in the pileus part 10-20 times were higher than stalk parts. After it was 2~4 hours preserve with salt, salinity appeared to proper density at 2.69~2.52%. The most suitable water content appeared after 4 hours drying in 40℃ in order to improve a taste and incense. It was longer preserve with salt, brightness was became lower in both jangaji and spices. When 1.5 month of acceleration experiment compared with room temperature three months, microbe inspection was stationary. Therefore, We fixed expiry date at 12 months considering stability of a product.

We used the linteus and oak-mushroom fungus that were a functionality mushroom, and We developed Korean cookies. Study of Korean cookies development used functionality mushroom mycelium culture rice. The optimal Proper water for culture rice were on 4 hours ideal. The optimal temperature for oak-mushroom mycelial growth of 25℃. The grain inoculum-source was the best in the oak-mushroom. And the lipid inoculum-source was the best in the linteus . Crude protein, crude fat, crude fiber appeared high at general component analysis results culture rice. but difference didn’t happen in crude ash. This culture rice of mushroom fungus contained glucose, sucrose in free sugar of the analysis results. Glucoses appeared high 10-50 degree compare with control at culture rice. This culture rice of mushroom fungus contained oxalic acid, tartaric acid, malic acid in total organic acid of the analysis results. Total organic acid appeared high compare with control at culture rice. K was detected highest during mineral element. Total mineral element content appeared high at linteus (411.86mg%) and oak-mushroom(410.10mg%) culture rice than control(220.80mg%). As a result of having measured chromaticity of culture rice, a L value and a(red color) value appeared high except red rice. Also, b(yellow color) value appeared high at linteus black rice than control. Sensuality evaluation results of the Korean cookies which used culture rice showed for the preference that control was higher.

The change on quality was measured to development functional steak sauce using superior oak-mushrooms with unique scent and functionality. Measure for Chromaticity according to method of addition indicated that L value of Experimental treatmentⅠ(oak-mushroom powder 1%, chopping 3%) was lower than Control and Experimental treatmentⅡ(Concentrated liquid 0.5%, chopping 3%). There was no significant difference between Control and two Experimental treatments in the result of pH measure. The total acidity showed that there was no significant difference between Experimental treatmentⅠ(1.544%) and Experimental treatmentⅡ (1.538%), but Experimental treatmentⅠand Ⅱ were lower than Control. The quantitative analysis of Chlorine showed that there was no significant difference among Experimental treatmentⅠ(4.19W/V%), Experimental treatmentⅡ(4.32W/V%) and Control(4.23W/V%). The viscosity on Experimental treatmentⅠand Ⅱ were more increased than Control. Microorganism was not discovered in the result of microorganism experiment of oakmushroom sauce. Experimental treatmentⅠwas higher preference than Experimental treatment Ⅱ.

This study was conducted to research the effect of Cryptomeria japonica sawdust and branch on the Production of Fruiting body of Pleurotus eryngii. Quantity of fruit body was lower in 5.2things/ bottle but yield of fruit body was higher in 3.5things/ bottle about big fruit body than Douglas-fir sawdust medium on C. japonica sawdust medium, so yield of fruit body was more 45g than Duglas-fir sawdust medium. But in the C. japonica branch sawdust medium, both quantity of fruit body and yield of fruit body was remarkably lower 13.3things/bottle, 42.8g/bottle respectively than Duglas-fir sawdust medium.
