Paper Title:
Structural Properties and Microstructures of SrTiO3/SrTi1-xNbxO3 Superlattices Grown by Ion Beam Deposition
  Abstract

Superlattice structure of SrTiO3 and Nb-doped SrTiO3 have been epitaxially grown on atomically flat surface of LaAlO3 substrates by ion beam deposition method. Epitaxial superlattices were grown at 800 °C in the presence of partial oxygen pressure under optimizing growth conditions. The Nb-doped SrTiO3 layers were varied from 2 to 15 unit cell thickness approximately, while SrTiO3 layers are maintained at 15 unit cell thickness with 10 periods. The superlattices with various Nb-doped SrTiO3 layer thicknesses were investigated using X-ray diffractometer (XRD) and atomic force microscope (AFM), in order to clearly understand structural properties and surface structure, which are significant for fabrication of the high quality superlattice structure.
