Cu（111）衬底上应变钴纳米岛的尺寸依赖表面态
Size-dependent Surface States on Strained Cobalt Nanoislands on Cu(111)
摘要：
对Cu（111）衬底上的Co纳米岛的低温扫描隧道谱研究表明，Co纳米岛的表面态随其尺寸的变化而变化。占据状态表现出相当大的向下的能量转移的岛的大小减小。被占领国的地位在各岛屿上也发生了重大变化。原子尺度的模拟和从头计算表明，所观察到的位移的驱动力是与纳米岛的尺寸依赖的介观弛豫。
英文摘要：
Low-temperature scanning tunneling spectroscopy over Co nanoislands on Cu(111) showed that the surface states of the islands vary with their size. Occupied states exhibit a sizeable downward energy shift as the island size decreases. The position of the occupied states also significantly changes across the islands. Atomic-scale simulations and ab inito calculations demonstrate that the driving force for the observed shift is related to size-dependent mesoscopic relaxations in the nanoislands.
