Appraisal on Textured Grain Growth and Photoconductivity of ZnO Thin Film SILAR

الملخص EN

ZnO thin films were prepared by successive ionic layer adsorption reaction (SILAR) method.

The textured grain growth along c-axis in pure ZnO thin films and doped with Sn was studied.

The structural analysis of the thin films was done by X-ray diffraction and surface morphology by scanning electron microscopy.

Textured grain growth of the samples was measured by comparing the peak intensities.

Textured grain growth and photo current in ZnO thin films were found to be enhanced by doping with Sn.

ZnO thin film having good crystallinity with preferential (002) orientation is a semiconductor with photonic properties of potential benefit to biophotonics.

From energy dispersive X-ray analysis, it is inferred that oxygen vacancy creation is responsible for the enhanced textured grain growth in ZnO thin films.
