Abstract
The adatoms, dimers and rest atoms in the three outermost atomic layers of the Si(111)-(7 × 7) surface are directly imaged with glancing Kikuchi electron holography. The applicability of Kikuchi electron holography to complicated multiple-emitter surfaces is evident. The three-dimensional relative positions of atoms on the Si(111)-(7 × 7) surface are in good accordance with the LEED-optimized DAS model.Keywords
