Characterization for surface morphology of Ag particles on ZnO film

In this paper, the influence of sputtering time of silver (Ag) particles and thermal treatment on the surface morphology of Ag particles on Zinc Oxide (ZnO) film has been studied. The size and density of Ag particles are measured using an atomic force microscopy (AFM) and a scanning electron microscope (SEM). The experimental results show that the size of Ag particles and the roughness (Ra) increases when sputtering time of Ag particles and thermal treatment temperature increases.
