Abstract
Zinc oxide (ZnO) nano-template layer was prepared using spin coating method. The coating layer was varied from 1 to 9 layers in this study. The surface morphology was observed by field emission scanning microscopy (FESEM). Meanwhile, the roughness and total grain boundary were characterised by atomic force microscopy (AFM). The thickness was increased from 90-310 nm, when the coating layer was increased. The grain size was observed below 50 nm. The surface roughness and its total grain boundary was increased and decreased, respectively.
