Abstract | ||
The structural, optical and electrical properties of ZnO:In thin films prepared by spray pyrolysis method are examined. The used spray solution (0.2M) was prepared by adding indium chloride InCl3 to the precursor of zinc acetate dissloved in mixed solution 80% H2O: 20%CH3OH. The XRD patterns for incorporated ZnO film with different concenteration of indium shows three addional peaks (100), (101) and (110) over the only one (002) appeared in pure ZnO. The intensities of these peaks are increased gradually with indium concentration while the (002) peak decrease to its minimum value at 3% In. The resistivity of ZnO films was improved by doping from 2.25x102 E.cm for undoped to the minimum value at 2% doping concentration 2.6x10-2 E.cm. The optical bandgap of all films has no change by In addition and shows sharp absorption edge at 380nm. | ||
