摘要: The scanning tunneling microscope has been employed to study the reduced SrTiO3(001) surface in ultrahigh vacuum. Topographic images show a change of structural ordering for annealed under three different conditions. In addition, our STM reveal row-like structures with spacings 12 and 20 A. observations are discussed terms formation intergrowths lamellae Srn + 1TinO3n +1; result accommodation oxygen titanium deficiencies.
