Abstract
Iron atoms were deposited on a carefully cleaned MgO (001) surface kept at room temperature, and growth mode of epitaxial film was studied by a conventional four-grid LEED-AES system. Deposition rate was about one angstrom per minute and residual gas pressure during the deposition was 5-6 × 10-9 Torr. Change rates of Auger peak-to-peak heights of substrate and deposit during the film formation were not similar. From these curves and some additional evidences, it seemed that the film grew up through the “Stranski-Krastanov mode”.
