Abstract

Neutron diffraction measurements were performed on amorphous carbon in order to investigate for the reason the anomalous electrical conduction. A change of the atomic structure at a function of temperature was determined. Using an arc vaporization method 1.0 g pure amorphous C sample was prepared at Gifu University, Japan. The experiment was carried out at the 7C2 spectrometer installed on the hot source of the reactor Orphee at Saclay. The momentum transfer range of 0.5 to 16 Å-1 was covered. The derived S(Q) exhibits a small difference due to the variation of the temperature. The radial distribution functions were also derived from these spectra. Finally, we present a possible explanation of the unexpected variation of d.c. conductivity at low temperature.
