Abstract
BaTiO3(BTO) and SrTiO3(STO) ultra thin films of 1-10 unit cell layers are s uccessfully fabricated on STO(0 0 1) substrates by laser molecular beam epi taxy. Measurements of atomic force microscopy (AFM), high-resolution transm ission electron microscopy (HRTEM) and X-ray small-angle reflectivity revea l that the surfaces and interfaces are atom-level-smooth. The unit cell lay ers and the lattice structure are perfect. (C) 2000 Elsevier Science B.V. A ll rights reserved.
