| 中文摘要 | the replacement of coronene monolayer on au (111) by 6-mercapto-1-hexanol (mho) was studied by in situ scanning tunneling microscopy (stm) in solutions. it was found that the rate of replacement depends strongly on the concentration of mho. the replacement finished within a second at a higher concentration of mho. at a lower concentration, the slow replacement could be followed by in situ stm. the replacement occurred initially near the elbow position of reconstructed au (111) with the formation of pits in a single or several missing molecules. with the proceeding of replacement, these small pits expanded, and the surrounding coronene molecules were gradually substituted by mho, which developed into ordered domains within a spatial confined environment. meanwhile, the reconstruction of au (111) was lifted. the replacement expanded fast along the reconstruction lines in the domain. for the fast replacement, a (root 3 x root 3) r30 degrees adlattice was observed, while a c(4 x 2) superlattice was observed for the slow replacement. |
