Abstract
We report on neutron diffraction study of a new form of conducting amorphous carbon up to Q ~ 14.5 Å-1. The bond distances from first two peaks in g(r) are 1.45 and 2.49 Å, very similar to those in sputtered truly amorphous carbon films (Li and Lannin, Phys. Rev. Lett. 65 (1990) 1905). The first coordination number is 3.1 (±0.1) indicating predominantly sp2 hybridisation (ideal no. = 3). However, S(Q) itself shows vestiges of (0 0 2), (1 0) and (1 1) peaks, typical of glassy carbon (Mildner, J. Non-Cryst. Solids 47 (1982) 391).
