STRUCTURAL AND MORPHOLOGICAL CHARACTERISTICS OF ZINC OXIDE THIN FILMS PREPARED BY SPRAY PYROLYSIS TECHNIQUE

ZnO thin films have been deposited on the glass substrates by spray pyrolysis method.  In this work we have studied the structural and morphological properties of ZnO thin films. Zinc acetate dihydrate was used as the precursor material. The structural and morphological properties of the films have been investigated by X-ray diffraction and atomic force microscopy characterization methods. Scherrer’s formula was used to calculate particle size. The thin films have (002) as the preferred orientation. The root mean square roughness of the films was calculated.
