Energetics of giant fullerenes and matrjoschka structures Article uri icon

abstract

  • The electronic structure of the giant fullerene family Cn, n = 60(ν %2b 1)2, was calculated for ν = 0,1,2,3,4. The calculation was carried out within the tigh-binding Hamiltonian in the Hartree-Fock approximation. We present results for the energy per atom as a function of size. An analytic expression is derived for the energy of giant fullerenes of arbitrary size in terms of the energy per pentagon, and plain and folded hexagons occuring in the truncated icosahedra. We computed also the energy of formation of multi-shelled matrjoschka structures and found that those are the most stable forms of carbon clusters. © 1994.
