摘要: Abstract In this study, the effects of several surfactants (Pb, Bi, and Ag) on homoepitaxial growth Fe(100) were studied compared. The reflection high-energy electron diffraction measurements clearly reveal that these enhance layer-by-layer Fe an Fe(100)– c (2 × 2)O reconstruction surface. dependence surfactant layer thickness suggests there exists a suitable amount induces smoother growth. Comparisons between atomic force microscopy images root-mean-square surface roughness films mediated by Pb Bi are considerably smaller than those Ag surfactant. Auger spectra show segregate at top It has been concluded effective for enhancing in homoepitaxy. same effect, but it is less efficient due to weak segregation Ag.
