Outline of Final Research Achievements

In this study, firstly, we clarify the correlation between orientation evolution and carrier transport of Al-doped ZnO (AZO) films deposited on glass substrates by direct current (DC) and radio frequency (RF) magnetron sputtering (MS) techniques. We found that DC-MS is possible to realize a high carrier transport by increasing the degree of (0001) orientation. As a solution, we deposited 10-nm-thick AZO films with well-defined (0001) orientation on glass substrates by RF-MS to successively deposit AZO films by DC-MS. Then, we achieved a near complete absence of the (10-11) reflection in AZO films. As a result, we realized the control of the carrier transport properties in polycrystalline thin film.
