? Nanocrystalline, uniform, dense, and adherent cerium oxide (CeO2) thin films have been successfully deposited by a simple and cost effective spray pyrolysis technique. CeO2 films were deposited at low substrate and annealing temperatures of 350?C and 500?C, respectively. 出版机构:Elsevier Science 刊物名称:Journal of Alloys and Compounds 出版时间:2011 ISSN:0925-8388 数据源:报刊文摘
? PbZr0.2Ti0.79Nb0.01O3 buffer layer can reduce the leakage current, coercive field and the asymmetry coercivity of the upper Bi0.89Tb0.11FeO3 film. ? The remnant polarization P r and coercive field E c for all Bi0.89Ti0.11FeO3 films show weak dependent on the film thickness. ? The 200-nm-thick Bi0. 出版机构:Elsevier Science 刊物名称:Journal of Alloys and Compounds 出版时间:2011 ISSN:0925-8388 数据源:报刊文摘

It was found that as-prepared Cu microcrystals were single crystals in nature and had a high crystallinity. They were mainly composed of disk-like and triangular Cu microcrystals with an average diameter of about 1?m. 出版机构:Elsevier Science 刊物名称:Materials Chemistry and Physics 出版时间:2011 ISSN:0254-0584 数据源:报刊文摘
