(English Abstract)
In this study, we prepared ITO thin films on Nb2O5/SiO2 double buffer layer using DC magnetron sputtering method and investigated electrical and optical properties with various substrate temperatures (room temperature ~ 400¡É). The resistivity showed a decreasing tendency, because crystallinity has been improved due to the enlarged grain size with increasing substrate temperature. ITO thin film deposited at 400¡É showed the most excellent value of resistivity and sheet resistance as 3.03¡¿10-4¥Ø¡¤cm, 86.6¥Ø/sq., respectively. In results of optical properties, average transmittance was increased but chromaticity (b*) was decreased in visible light region (400~800nm) with increasing substrate temperature. Average transmittance and chromaticity (b*) of ITO thin film deposited at 400¡É exhibited significantly improved results as 85.8% and 2.13 compared to 82.8% and 4.56 of the ITO thin film without buffer layer. Finally, we found that ITO thin film introduced Nb2O5/SiO2 double buffer layer has a remarkably improved optical property such as transmittance and chromaticity due to the index matching effect.
