| 中文摘要 | Structural properties of Pb islands grown on graphene/Ru(0001) at various deposition temperatures (T-D) and annealing temperatures (T-A) are investigated by a low-temperature scanning tunneling microscope. Single-layer Pb islands with a 2 X 2 reconstruction are only formed at T-D of 80 K and disappear with post-annealing to room temperature (RT). It is revealed that a morphological transition of the Pb islands takes place, from irregular shapes to a hexagonal equilibrium shape, with increasing T-D or T-A to RT. Moreover, Pb islands grown at T-D of RT are larger than those grown at a T-D of 80 K and annealed to RT. All Pb islands with a T-A or T-D of RT are (111)-faceted with thicknesses of even-numbered atomic layers and exhibit a weak interaction between Pb and graphene. |
