초록

ZnO thn films are grown on five kinds of oxide substrates including $c-Al_2O_3(0001),\;r-Al_2O_3(01-12)$, MgO(100), MgO(111), $NdGaO_3(110)$ by rf magnetron sputtering and effects substrate types on properties of ZnO thin films ate investigated. In order to compare the substrate effects one growth condition is selected and all the films are grown by the same growth condition. Structural and optical properties of the ZnO films ate different depending on the substrates although the films ate not epitaxial but polycrystalline. The ZnO film grown on $NdGaO_3(100)$ substrate shows the best overall properties among the films grown on substrates investigated in this study.
