Abstract :
Using atomic force microscopy, it has been found that nanotube-like structures can be formed naturally on highly oriented polygraphite (HOPG) surfaces by “peeling” the graphite sheet in air at room temperature. These structures were often distributed near the steps, and are occasionally found on flat terraces. The apparent diameters of these tubes range from several to tens of nanometers. The mechanism of the formation process is discussed.
