Abstract:

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