中文摘要 | We demonstrate the formation of well-ordered arrays of Mn nanoclusters of nearly identical sizes on a Si(lll)-(7×7) surface. The Mn atoms are found not to react with the Si substrate at temperatures below -260℃. At room temperature, the Mn clusters occupy both halves of the (7×7) unit cell and arrange themselves into a honeycomb structure, whereas at a temperature of 258℃, they exclusively occupy the faulted half of the unit cell and form an array with hexagonal symmetry. The self-organization process of the nanocluster array of Mn is different from that previously reported for the group-ⅢA metals, due to stronger Mn-substrate and Mn-Mn interactions. |
