摘要
The lateral displacements in the Ge(001)-(2x1)surface reconstruction have been determined using transmission electron diffraction (TED). The best-fit model includes displacements extending six layers into the bulk. The atomic positions found agree with X-ray studies to within a few hundredths of an angstrum. With the positions determined so precisely, it is suggested that the Ge(001)(2x1) surface can now serve as a standard for comparison with theoretical surface structure calculations. The results from the currently available theoretical studies on the surface are compared with the experimentally determined structure. (C) 1997 Elsevier Science B.V.
