The kinetics of carbon nanostructure 2D–3D transformation
Tóm tắt
The gas-phase process of formation of carbon nanostructures in an arc discharge plasma is considered. Most attention is paid to one of the key stages of the formation of these nanostructures, the transformation of plane structures into three-dimensional. The rolling up of a plane graphite sheet into a nanostructure similar to fullerene or a nanotube was simulated by the molecular dynamics method. The simulation data were described by a mechanism based on the generation of defects on the surface of the sheet. A set of elementary system structural transformations was determined, and the kinetic scheme describing the behavior of defects constructed. The lowest temperature of the observation of rolling up in practice was estimated.
