摘　　要：利用超高真空扫描隧道显微镜(UHV-STM),原位研究铜(110)c(2×1)-O纳米模板调控下的富勒烯分子的吸附行为及自组装纳米结构。结果表明,富勒烯分子在铜(110)c(2×1)-O模板上主要有两种吸附位点:-O-CuO-链上的铜原子和相邻的-O-Cu-O-链之间,并且富勒烯分子沿着-O-Cu-O-链自组装成线性链。进一步的热处理可将该类线性分子链转变成沿着[1 16]和[116]方向的六角密排岛。Adsorption behaviors and self-assembly structures of fullerene induced by Cu（110）c（2 × 1）-O template have been investigated by ultrahigh-vacuum scanning tunneling microscopy （UHV-STM ）. Fullerene molecules prefer to adsorbing on the top of the Cu atoms at-O-Cu-O-chain or between two adja-cent-O-Cu-O-chains,as a consequence,the molecular chains are formed along the-O-Cu-O-chains on the template.Thermal annealing process drives such linear molecular chains into well-ordered close-packed islands with a distorted hexagonal structure oriented along [116]or[116]direction.
