Electrical properties of two-dimensional fullerene matrices

The electrical properties of two-dimensionally polymerized C-60 fullerenes were studied. Fullerene matrices consisting of randomly oriented domains ar e compared to the highly-oriented rhombohedral phase. The conductivity of t he randomly oriented polymers obeys the Arrhenius law and can be described in a multiple trapping model. The oriented phase of polymeric C-60 shows a distinct anisotropy in the electrical properties with a metallic-like in-pl ane conductivity at high temperatures. (C) 2001 Elsevier Science Ltd.
