“…From these figures it was clear the C 60 cage survived the reduction process as all C 60 modes are present in the spectra. As with the thin film zinc-C 60 complex, there was peak broadening and downshifting, the largest amount again occurring with the H g (7), A g (2), and H g (8) modes. By deconvoluting the A g (2) mode Figure 2b was generated and two subpeaks were more discernable.…”

“…For every 6 cm -1 the peak was downshifted is suggestive of the C 60 complex holding an additional electron (13)(14)(15). Comparing the thin film in Figure 1b to neutral C 60 in Figure 1a, strong peak broadening can be seen in the H g (7), A g (2), and H g (8) modes. Using peak fitting software, the A g (2) mode was deconvoluted in Figure 2a.…”

“…Neutral fullerenes exhibit very low electrical conductivities while fullerides with an alkali counter ion can have electrical conductivities on the order of 10 5 Ω/m (8,9). Metal-fulleride materials can be analogous to a metal salt if the negatively charged fulleride counterion is considered as a "superatom."…”

A wide variety of fullerene based materials has shown great promise for energy conversion applications such as thermoelectric and photovoltaic devices. With their intrinsically low thermal conductivities, fullerene based materials may offer several advantages for thermoelectric applications over traditional inorganic based thermoelectric materials. Fulleride materials have already shown electrical properties spanning from the insulative to superconductive regimes.In order to rapidly advance the development of new transition metal fullerides, a thin film approach, novel wet chemical method, and chemical vapor deposition method were explored. Materials formed from these synthesis routes have been found to retain their low thermal conductivities. A present focus is on Raman spectral analysis for preliminary determination of the materials' stoichiometries.
