In this paper using Density Functional Theory (DFT), the principal carbon allotropic crystalline structures (Diamond, graphite, nanotube y fullereneC60) were simulated. The results showsdiamond sp3 bonds formation between carbon atomsand low reactivity, indicating low probability of lateral compound formation and high mechanical properties. Interplanar weakness was evidentin graphite structure,...
