초록

The 2 wt.% Al-doped ZnO(AZO) thin films were fabricated on PET substrates with various RF power 20, 35, 50, 65, and 80W by using RF magnetron sputtering in order to investigate the structure, electrical and optical properties of AZO thin films in this study. The XRD measurements showed that AZO films exhibit c-axis orientation. At a RF power of 80W, the AZO films showed the highest (002) diffraction peak with a FWHM of 0.42. At a RF power of 65W, the lowest electrical resistivity was about $1.64{\times}[10]$ ^(-4) ${\Omega}-cm$ and the average transmittance of all films including substrates was over 80% in visible range. Good transparence and conducting properties were obtained due to RF power control. The obtained results indicate that it is acceptable for applications as transparent conductive electrodes.
