Stm Study Of Vicinal Structures On Au(100)
Résumé
We present STM observations of `'magic'' vicinal areas on a Au(100) sample. The surface displays the well-known quasihexagonal reconstruction on flat (100) as well as on vicinal regions. In these regions, it is observed that the terrace widths are strongly related to the reconstruction period. In addition, the steps present diatomic kinks periodically situated about every 50 angstrom. An atomic model, accounting for these observations is presented. It is consistent with most of the published results, though offering a new explanation for the measured terrace widths.
