摘要：

A series of the toroidal cage forms of graphitic carbon is proposed. They have local topological structures of positive Gaussian curvature (for instance C60) and of negative Gaussian curvature. The toroidal forms consist of fivefold, sixfold, and sevenfold carbon rings. The cohesive energies of the tori (C(n), where n ranges from 120 to 1920), which are calculated by molecular dynamics, indicate that these structures are energetically more stable than C60. These structures are also found to be thermodynamically stable by means of a finite-temperature simulation.
