摘要：

Folded graphitic sheets have been produced and studied using a scanning tunnelling microscope. Folds of one and two layers are observed at steps on highly oriented pyrolytic graphite. Images at atomic resolution show that the folding axes lay along the [210] or [100] directions resulting in AB- or AA-stacking of the folding sheets on the graphite surface, respectively. The stability of the observed structures is studied and the attractive inter-plane energy is found to be larger than the repulsive folding energy. (C) 1998 Elsevier Science B.V. All rights reserved.
