Zinc oxide is a versatile material with excellent optical, electrical and piezoelectrical properties and has been applied to antireflection coatings, transparent electrodes in solar cells, surface acoustic wave devices, pyroelectric devices, gas sensors, varistors and electro- and photoluminescent devices. Nanostructured ZnO thin films can be achieved by pulsed-laser deposition. Key processing parameters of chamber pressure and substrate temperature have been investigated and correlated with various morphologies of nanostructure. The characterization was made using X-ray diffraction and scanning electron microscope.
