摘要：
In-doped Zn0.9Mg0.1O (0 similar to 5 mol%) films on glass substrate were successfully grown by a spray pyrolysis method at 500 degrees C. The c-axis orientation became weak with increasing indium concentration. This indicated that In-doping caused the degree of crystallinity of the Zn0.9Mg0.1O films to decrease. Indium atoms could be acted as a donor type impurity because electrical conduction types in the undoped and Indoped films indicated all n-types and In-doping caused the resistivity to decrease and carrier concentration to increase. Furthermore, In-doping caused the number of nonradiative recombination centers to increase because photo luminescence intensity decreased with increasing indium concentration.
