BaTiO 3/SrTiO 3 superlattices were grown on SrTiO 3(00l) substrates by laser molecular beam epitaxy. For the constituent layers of BaTiO 3 and SrTiO 3, two-dimensional layer-by-layer growth could be achieved and atomically flat surfaces were preserved. However, their growth behaviors were somewhat different, which might come from strain effects. Such a difference was also revealed from the structural properties of the superlattices. X-ray diffraction measurements showed that the superlattices were grown with the desired strutures and abrupt interfaces.
