Abstract
Defects in Ruddlesden-Popper phase CaO·[(CaMnO3)]4 epitaxial films grown on SrTiO3 (001) by pulsed laser deposition have been investigated using high angle annular dark field imaging in an aberration-corrected STEM. The stacking faults perpendicular and parallel to the substrate formed during the growth are discussed in detail. The desired n = 4 RP phase is imaged and chemically analyzed at the atomic scale using electron energy loss spectroscopy.
