Abstract
Non-stoichiometric potassium fulleride nanowires, KnC60, intercalated into the pores of mesoporous niobium oxide (see Figure), show conductivity maxim a that are different from those of bulk fullerides. An interesting result t hat is attributed to an electronic transition in the material to a cooperat ive state, in which the structure is no longer acting as a one-dimensional system, is obtained at n = 4.1.
