英文摘要	High quality SrTiO3 thin film on (1 1 0) DyScO3 substrate is grown by laser molecular beam epitaxy. The lattice strain resulting from the lattice mismatch between the substrate and the film relaxes gradually with depth. A critical thickness of about 30 nm for sharp strain relaxation is observed. The dislocation density, which forms to relax the lattice strain, is estimated to be about 10(8) cm(-2) according to the high resolution x-ray diffraction. The edge dislocation density is slightly larger than that of the screw ones.
