A modified phenomenological model is proposed for calculating the formation energy of carbon nanoclusters which makes it possible to analyze the regions of existence of clusters of various forms. A new parameter of the model, which corresponds to passivation of broken carbon bonds, affects the shape of the equilibrium optimum clusters, i.e., those having a minimum energy for a fixed number of atoms. Analytic dependences of equilibrium-configuration states determining the existence of spheroidal closed clusters, nanopipes, and fragments of a graphite plane, on the broken-bond energy parameter obtained in this model are presented.
