 note = {We present transmission electron microscopy and Raman spectroscopy of amorphous carbon (a-C) films deposited on clean surfaces of nickel (Ni) nanoparticles at room temperature. In the Raman spectrum measured from the a-C film on the Ni nanoparticles, the broad peaks of the D and G modes appeared at 1388 and 1582 cm−1, respectively. The high-resolution images and the corresponding filtered inverse fast Fourier transformed images of the a-C film on the individual Ni nanoparticles showed that the a-C film only around the Ni nanoparticles formed disordered graphitic layers, similar in structure to carbon black, without heat treatment. The present observation suggests that spontaneous graphitization of a-C on the clean surfaces of the Ni nanoparticles occurs at room temperature., Proceedings of the 10th International Symposium on Atomic Level Characterization for New Materials and Devices (ALC 2015),Matsue, Japan, 25-30 October 2015},
