Abstract
AbstractSingle crystal films of both rocksalt CoO and spinel Co3O4 were epitaxially grown with (001) orientations on MgO(001) substrates by pulsed laser deposition from CoO targets. The samples were characterized with low energy electron diffraction to determine the parallel orientation of the films with respect to the substrate, and x-ray diffraction to determine the perpendicular structure of the films. Both films were determined to have undergone tetragonal distortions, although to different degrees, due to the biaxial stress present in these epitaxial films.
