Аннотация:Surface morphology and controllable growth of C-60 films on a semi-metallic Bi(001)/Si(111) template surface were studied under ultra-high vacuum conditions using scanning tunneling microscopy. Submonolayer, monolayer and thick layer coverage were imaged with atomic resolution. It is shown that the most favorable sites for C-60 nucleation are domain boundaries and double steps whereas the surface with one monolayer coverage revealed a characteristic modulation pattern coming from the epitaxial relation between C-60 and Bi unit cells.
