After the Rb 3C 60 thin film with a thickness of nanometers has formed on the surface layers of the C 60 single crystal, the excess depositions of Rb do not induce the bulk-like fcc to bct or bcc structure transitions at room temperature.

• 当数纳米厚Rb3C6 0 薄膜在C6 0 单晶 (111)解理面形成后 ；室温条件下进一步沉积Rb至样品表面不产生fcc到bct或bcc结构相变 .
