我们研究了在单价金属原子吸附过程中，费米表面和价带的表面电子结构的演变，电子填充到二维自由电子样表面态；银和碱金属；Nad在Sis111dI33I3-Ag表面。小电子袋的费米表面（费米环）随着吸附而不断生长。最终，通过0.1-0.2层吸附Ag或Na形成I213I21上层结构时，发现费米环大于I213I21表面布里布鲁带sSBZd，并服从I213I21的周期性折叠。作为一个
We have studied the evolutions of surface electronic structure sFermi surfaces and valence bandsd by electron filling into a two-dimensional free-electronlike surface state, during adsorptions of monovalent metal atoms snoble metal; Ag, and alkali metal; Nad on the Sis111dI33I3-Ag surface. The Fermi surfaces sFermi ringsd of a small electron pocket grow continuously with the adsorption. Eventually, when the I213I21 superstructure was formed by 0.1–0.2 monolayer adsorption of Ag or Na, the Fermi ring is found to be larger than the I213I21-surface Brillouin zone sSBZd, and to be folded by obeying the I213I21 periodicity.
