中文摘要	We show by first-principles calculations two types of magnetic magic Mn clusters on the Si(111)-(7x7) surface. The first is a small triangular Mn-7 cluster stabilized by the solid-centered Mn-Si-3 bonds on the top layer, and the second is a large hexagonal Mn-13 cluster favored by the confining potential wells of the faulted half unit cells on the Si(111) surface. These two structural models are distinct from that of the planar group-III clusters on Si(111) and produce simulated scanning tunneling microscopy images in reasonable agreement with recent experimental observations. These results offer key insights for understanding the complex energetic landscape on the Si(111)-(7x7) surface, which is critical to precisely controlled growth of Mn nanocluster arrays with specific size, magnetic moment, and good uniformity.
