摘要：
We demonstrate that quantum size effects play a crucial role in the row structure of metal-induced Si(111) reconstruction by identifying the 'magic' widths of the metal adsorbates with the minima of electron energy as a function of adsorbate width. Without any adjustable parameters, we obtain accurate agreement with all recent results for Si(111)-4 x 1-In and Si(111)-3 x 1-M (M = Li, Na, K, Rb, Ag) structures. This new and simple physical picture of electron energies in metal adsorbates provides a universal quantitative model for describing the row structures of metal-induced Si(111) surface reconstructions.
