Abstract: Zinc oxide thin films were obtained on Pt-coated silicon, r-cut sapphire and MgO substrates by laser ablation of a Zn target in oxygen reactive atmosphere, the oxygen being supplied either by a standard gas inlet valve or from a radiofrequency (RF) oxygen plasma. The influence of the deposition parameters, i.e., laser wavelength (266 nm, 355 nm, 1064 nm), laser fluence (1.5-20 J/cm 2 ), oxygen pressure (1-60 Pa), and of RF plasma beam addition on the morphological properties of zinc oxide films was particular…
