title: Formation of fullerides and fullerene-based heterostructures.
abstract: Two potassium fulleride phases, metallic K(3)C(60) and nonmetallic K(6)C(60), are formed when potassium is incorporated into thin C(60) films under ultrahigh vacuum conditions. Phase separation is observed for intermediate stoichiometries. Results obtained for the C(60)-K(3)C(60) heterostructure demonstrate that it is stable against potassium migration from the K(3)C(60) phase. In contrast, the C(60)-K(6)C(60) interface is not stable and K(3)C(60) is formed.
