This study investigates the effect of Li content on the structural, optical, and electrical properties of sol-gel LiZnMgO films by x-ray diffraction, scanning electron microscopy, photoluminescence, and conductivity measurements. A dependence of crystallite size and conduction type upon Li content has been found. The abnormal shift of the (002) diffraction peak position determined from x-ray diffraction measurements and conduction type determined by Hall effect measurements are closely related to the defects/different defect types. It is shown that n-type conversion of LiZnMgO films is a result of the increase in the donor density based on the change in stoichiometry.
