제목 Hydrogen effect of ZnO:Al by RF magnetron sputtering in H2/Ar atmosphere
초록 AZO (ZnO:Al) films were fabricated by RF magnetron sputtering in H2/Ar (5% H2) atmosphere, and electrical and optical properties were investigated. The substrate temperatures were varied at RT, 100℃, 150℃ and 200℃. The resistivity of the films grown in H2/Ar (5% H2) were reduced from 7.67 10-4 to 5.95 10-4 in comparison with that of films deposited in Ar (100%) and the transmittance in wavelength range of 200~500 nm were over 93%.

Changes in the electrical properties of the ZnO:Al films are shown in Fig. 1. The electrical properties of the AZO films improved to 5.95 10-4 in H2/Ar (5% H2). The reason is that hydrogen plays an important role in n-type conduction as a donor [1-2]. Fig.2 shows optical transmittance spectra in the wavelength ( ) range 300 ~ 800 nm. It can be seen that the average optical transmittance in the visible light wavelength range is over 93%.
