Popis:	Artificial SrTiO3/SrO superlattice thin films epitaxially grown on SrTiO3 substrates were fabricated by pulsed laser deposition. The artificial superlattices were designed and fabricated by introducing a Ruddlesden-Popper (RP) layer periodically. The intensity of reflection high-energy electron diffraction (RHEED) patterns during the growth of the superlattices increased at the deposition of SrTiO3 layers and decreased at the deposition of the SrO monolayer, alternately. The gradual intensity decrease of RHEED reflection during SrO layer deposition is attributable to the island growth of SrO. The different type of RP layers normal to the film surface, observed in a high-temperature deposited superlattice, may originate from the higher diffusion condition and island growth of SrO.
