Ar/H2 mixed atmosphere, which effectively inhibited the formation of NiO, was used as pre-depositing gas before CeO2 films were grown in Ar and 02. At 700 ℃ under the total pressure of 26 Pa,the pure c-axis orientation tilm was obtained. X-ray θ-2θscan, pole figure and φ-scan were used to observe the microstructure of the buffer layer. The resuits show that CeO2 film has strong cube texture and the FWHM is 9°. In addition, the CeO2 film is dense and crack-free.展开更多

Ar/H2 mixed atmosphere, which is used as pre-depositing gas, can effectively inhibit the formation of NiO. In addition, the linear relationship between pre-depositing time and total depositing time is required to ensure the epitaxial growth of the films. The growth conditions of CeO2 and Y2O3 were comparatively studied, and it is found that the windows of substrate temperatures and pressures for CeO2 films are wider than that for Y2O3 films.展开更多
