Comment on "Stability of Small Carbon-Nitride Heterofullerenes"

Abstract

We comment on a recent paper [D. Schultz et al, Phys. REv. Lett. 90, 015501 (2003)]. We argue that a highly systematical investigation is needed to determine the most stable structures of both pristine and N-substituted fullerenes.
