摘要：

Atomically regulated layers of perovskite oxides and alkaline earth cuprates were fabricated by laser MBE with the aid of RHEED intensity oscillations clearly observed during film growth. A ceramic superlattice composed of lattice-matched SrVO3-x and SrTiO3-y perovskites was prepared on an atomic scale by counting the number of RHEED oscillation. In situ RHEED and XPS analyses indicate that the interface between the laterally grown SrCuO2-z epitaxial film and the SrTiO3(001) substrate has a transition layer of about 1 nm thick, which apparently reflects an inhomogeneous growth manner at the initial stage.
