Effect Of Oxygen

The effect of oxygen partial pressure on the preferred orientation of CeO2 thin films was investigated by depositing CeO2 thin films and Pb(Zr, Ti)O3/CeO2 multilayers on Si (100) substrates by pulsed laser deposition. CeO2 thin films exhibited random polycrystalline grain structures at high oxygen partial pressure (≥40 mtorr), a result that is contrary to previous reports. The relationship of the preferred orientations observed between Pb(Zr, Ti)O3 films and the CeO2 layer underneath confirmed that random polycrystalline CeO2 was obtained at high oxygen partial pressure. It was suggested that x-ray diffraction data in previous reports might have been misinterpreted.

Structural And Optical Properties

VO2films were grown on sapphire substrates by pulsed laser deposition (PLD), and the structural and optical properties of as-grown films were investigated by X-ray diffraction (XRD), field effect scanning electron microscopy (FESEM), photoluminescence (PL), and optical-transmission measurements. The oxygen partial pressure in the growth chamber was found to be the key factor deciding the microstructure and properties of as-deposited VO2films, and its effects and corresponding mechanism were investigated systemically. Results indicated that dense and uniform VO2films with smooth surface were achieved by PLD under optimized oxygen partial pressure. Strong blue emission peaks were observed in room temperature photoluminescence (PL) spectra. Excellent selective optical-transmission of the VO2thin films from 200~3000 nm were also recorded at room temperature.
