Electrical properties of the C{sub 60}(OH){sub 10}/Au contact have been studied by measuring its current-voltage characteristics in the temperature range of 300–500 K. The Schottky barrier of the C{sub 60}(OH){sub 10}/Au contact was confirmed to be 0.70±0.02 eV from Arrhenius plots of the current-voltage characteristics measured at various bias voltages as well as various preparation conditions of the C{sub 60}(OH){sub 10} material. Significant effect of the applied electric field on the barrier height has not been observed in the range of 0.1–2.0 MVm{sup −1}. The effects of both the charge transfer from C{sub 60} cage to OH groups and the crystallinity of the C{sub 60}(OH){sub 10} material on the Schottky barrier were discussed on the basis of x-ray photoemission spectroscopy and x-ray diffraction analyses.
