    Abstract

    In the present work the clean Ge(001)-(2×1) surface is studied with scanning tunneling microscopy. Many different dimer-vacancy (DV) defects and complexes are seen on the surface. Among them the complex consisting of a missing dimer, a twin missing-dimer, and a dimer between them, i.e., the (1+2)-DV complex, comprises a great majority. Our line scan of the (1+2)-DV complex strongly supports the structural model proposed recently by Wang, Arias, and Joannopoulos for the (1+2)-DV complex on the Si(001) surface. In addition, some information on the interactions between neighboring dimers are also obtained and discussed, and some differences between Ge(001) and Si(001) surfaces are noted.
