Abstract
The structural evolution of nanocrystalline ZnO films on copper substrates synthesized via pulsed laser deposition was observed with increasing thickness controlled by deposition time. Scanning electron microscopy images indicate an increase in the average grain size. All the films are polycrystalline with the hexagonal wurtzite structure. X-ray diffraction patterns prove the orientation of the crystals to become better with an increase in film thickness. Raman measurements show three optical normal modes of crystalline ZnO indicating wurtzite structure. The line-width variation of the E2high mode reveals the structural improvement of the nanocrystalline ZnO films. The spatial correlation model was applied to analyze the structure evolution of the films. Different electron field-emission current densities are observed during the structural evolution of nanocrystalline ZnO films.
