제목 투명전극용 ZnO:Al 박막의 전기광학적 특성에 미치는 밀도의 영향
초록 ZnO (zinc oxide) films have been actively investigated as transparent electrode materials for display. We report the influence of the film density on electro-optical properties of Al-doped ZnO thin films. Al-doped ZnO (AZO) thin films were deposited on corning glass #1737 substrates by d.c. magnetron sputtering method at 150 ℃ using ZnO-2 wt% Al2O3 ceramic target. Argon was introduced near the substrate. The films were deposited in the working pressure from 1 mTorr to 10 mTorr.


The film density was varied with working pressures and it was the highest at the pressure of 1 mTorr. It was explained by atomic bombardment effect. XRR (X-Ray reflectivity) method was used to investigate the variation of the density. The resistivity was the lowest at the point of 1 mTorr. Hall effect measurement analysis was done to understand the variation of the resistivity. It was found that carrier mobility is a dominant factor for controlling the resistivity more than the carrier concentration. Optical property was measured by UV-vis-nir spectrometer.
