摘要：

Vicinal Si(100) (4 degrees) shows perfectly ordered terraces with a width of 4 nm separated by double steps. Adsorption of Au at 800 degrees C results in a dramatic change of the step morphology: the surface decomposes into areas which are perfectly Bat with a (100)orientation and [119]-facets, which compensate the macroscopic miscut. Macroscopic super terraces with a width of 400 nm up to 4 mu m are formed, which are extremely straight with a length limited only by the size of the sample. (C) 1998 Elsevier Science B.V.
