Abstract:
In this work used different substrates the glass substrate and porous silicon substrate prepared by electrochemical etching. Pur ZnO thin film and doped with indium prepared by chemical spry pyrolysis technique. Polycrystalline ZnO thin films showed a preferred orientation in the (002) direction perpendicular to the substrate. The intensity decreased significantly with increased indium concentration and the preferred orientation changed from (002) to (101) on the glass substrate. SEM pictures showed a close packed morphology for both un- doped and In-doped films, and decrease in grain size with doping clearly seen. AFM pictures showed the smoothness decreases with increase indium concentration 1% and then become very smooth with indium concentration 3% for all glass substrates
