Submonolayer films on a Si(111) surface under low-energy ion bombardment

The kinetics of deposition for monomolecular submonolayer films on a Si(111) surface is studied via low-energy electron diffraction with measurements of the intensities of diffraction reflection and the elastic background. The degree of structural perfection in growing films is estimated for alkali-metal silicides and silicon from low-energy beams. The optimum energy and dose intervals of silicide film formation are determined.
