Comparative study of dimer vacancies and dimer-vacancy lines on Si(001) and Ge(001)

C. V. Ciobanu, D. T. Tambe, V. B. Shenoy

Although the clean Si(001) and Ge(001) surfaces are very similar, experiments to date have shown that dimer-vacancy (DV) defects self-organize into vacancy lines (VLs) on Si(001),…
