Abstract : A brief study has been carried out to investigate the structure of pristine and intercalated thin benzene derived graphite fibers. High resolution transmission electron microscopy techniques were used. The fibers used for this study were prepared by thermal decomposition of benzene onto a substrate seeded with metal particles. The unique feature of the fibers used in this study is that their diameter is only 170 manometers. Fibers used in earlier studies and for most technological applications have generally had diameters more than an order of magnitude larger. Study of the physics of size effects in carbon fibers was a prime motivating force for the current investigation. Keywords: Ultra thin carbon fibers, High resolution electron microscopy, Studies of thin carbon fibers.
