چکیده انگلیسی
The article deals with structural properties of ZnO thin layers prepared on Si (111) by pulsed laser deposition at different pressures (1-35 Pa) of ambient oxygen in the deposition chamber. The growth temperature was 400 °C and a pulsed Nd:YAG laser was used at a wavelength of 355 nm. Two parallel sets of samples deposited by ablation of different targets (a sintered ceramic pellet of ZnO and a pure metallic Zn target) were examined. The samples were characterized by different analytical methods: scanning electron microscope (SEM), secondary ion mass spectroscopy (SIMS), and X-ray diffraction (XRD). The prepared layers exhibited columnar structure and uniform preferred c-axis orientation. The results showed that deposition of the high quality of ZnO films fabricated from both targets is comparable, except for those obtained at low (1 Pa) pressures.
