Donald W. Brenner,Olga Shenderova,Judith A. Harrison,Steven J. Stuart,Boris Ni,Susan B. Sinnott +5 more
TL;DR: Brenner as mentioned in this paper presented a second generation potential energy function for solid carbon and hydrocarbon molecules that is based on an empirical bond order formalism, allowing for covalent bond breaking and forming with associated changes in atomic hybridization within a classical potential, producing a powerful method for modelling complex chemistry in large many-atom systems.
