摘要：

The 6 x 6 and root39 x root39 phases of Ag/Ge(111) have been studied by scanning tunneling microscopy (STM). Surface atomic structures of the 6 x 6 and the root39 x root39 phase are proposed in terms of additional Ag adatoms on top of a root3 x root/3 layer described by the honeycomb-chain-trimer (HCT) model. By varying the STM tip bias, the reconstruction can be changed reversibly between the root39 x root39 and the 6 x 6 phase. Besides the switching between two different phases, it is also possible to flip the domain orientation of the root39 x root39 phase. The mechanisms of the reconstruction transformation have been discussed in terms of the role of the STM tip. (C) 2003 Elsevier B.V. All rights reserved.
