Reflection high-energy electron diffraction oscillations during growth of metallic overlayers on ideal and nonideal metallic substrates

Oscillations in the intensity of reflection high-energy electron diffraction (RHEED) patterns are observed for Fe, Ni, Au, and Mn overlayers epitaxially grown in various combinations on Fe, Ni, Au, Ag, and Ru substrates. Fe whickers are nearly ideal substrates for the study of RHEED and RHEED oscillations during growth. Oscillations for metals and semiconductors show similar dependence on temperature, diffraction angles, and surface impurities.
