摘要
Thin films of transparent conducting aluminum-doped ZnO have been deposited using a sol-gel process. The dependence of electrical characteristics upon aluminum concentration in the films and upon post-deposition heat treatment in vacuum was examined. The effect of changing the aluminum-to-zinc ratio from 0% to 4.5% (atomic) and the heat treatment temperature in vacuum has been thoroughly investigated. Resistivities of (7-10) X 10(-4) OMEGA cm have been achieved for ZnO:Al films with Al/Zn ratios of 0.8 at.% heated to 450-degrees-C in vacuum. Transmittance in the visible region is above 900/o. Similar results were obtained using aluminum chloride and aluminum nitrate as the aluminum precursor.
