Abstract
Grazing scattering of 25 keV He+-ions during homoepitaxial growth of Fe on Fe(100) is reported. The angular distribution of scattered projectiles depe nds on the coverage in a characteristic way owing to the periodic change in surface morphology. An analysis based on a classical description for ion t rajectories enables one to derive quantitative information on growth mode a nd growth kinetics. At 550 K pronounced oscillations show near perfect laye r-by-layer growth persisting for many layers. (C) 1999 Elsevier Science B.V . All rights reserved.
