中文摘要	The thickness dependence of microstructures of La0.9Sr0.1MnO3 (LSMO) thin films grown on exact-cut and miscut SrTiO3 (STO) substrates, respectively, was investigated by high-angle X-ray diffraction (HXRD), X-ray small-angle reflection (XSAR), X-ray reciprocal space mapping and atomic force microscopy (AFM). Results show that the LSMO films are in pseudocubic structure and are highly epitaxial [001]-oriented growth on the (001) STO substrates. The crystalline quality of the LSMO film is improved with thickness. The epitaxial relationship between the LSMO films and the STO substrates is [001](LSMO)parallel to[001](EXACT-STO), and the LSMO films have a slight mosaic structure along the q(x) direction for the samples grown on the exact-cut STO substrates. However, an oriented angle of about 0.24 degrees exists between [001](LSMO) and [001](MISCUT-STO), and the LSMO films have a mosaic structure along the q(z) direction for that grown on the miscut STO substrates. The mosaic structure of both groups of the samples tends to reduce with thickness. The diffraction intensity of the (004) peaks increases with thickness of the LSMO film. The XSAR and AFM observations show that for both groups, the interface is sharp and the surface is rather smooth. The mechanism was discussed briefly. (c) 2007 Elsevier B.V. All rights reserved.
