Abstract:
The theory presented enables calculating the cohesive energy and line energy (the work of formation of the unit border line length) of graphene from the first-principles data, which also yields estimate of the line tension of graphene at zero temperature. Contributions from chemical bonds and dispersion forces have been estimated separately to give a summary value of 16.7 × 10(-10) J m(-1) for the line energy of graphene. The significance of line energy and line tension for nanotube formation is discussed.

When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...
