Abstract Using scanning tunneling microscopy (STM) observation, interaction of yttrium (Y) atoms with the C60 fullerite films has been studied. It has been found that adsorbed Y atoms avoid clustering and are incorporated in the C60 film as individual atoms occupying the octahedral voids of the fullerite crystal. As a result of a charge transfer from the Y atom, the three neighboring surface fullerenes look more bright in the filled-state STM images. Yttrium atoms are tightly bound in their sites and neither move laterally nor float to the film surface upon subsequent overgrowth of C60 layers.

钇原子与 C60 富勒体薄膜的相互作用

摘要 使用扫描隧道显微镜 (STM) 观察,研究了钇 (Y) 原子与 C60 富勒体薄膜的相互作用。已经发现,吸附的 Y 原子避免了聚集,并作为单独的原子被结合到 C60 膜中,这些原子占据了富勒体晶体的八面体空隙。由于来自 Y 原子的电荷转移,三个相邻的表面富勒烯在填充状态的 STM 图像中看起来更亮。钇原子在它们的位置紧密结合,并且在随后的 C60 层过度生长时既不会横向移动也不会漂浮到薄膜表面。
