Abstract
A new empirical potential for both diamond and graphite structures, in spired by the previously published work by Heggie [J. Phys. Condensed Matter 3 (1991) 3065; Carbon 30 (1992) 71], has been developed. This p otential accounts for the weak attractive interaction between planes a s well as for a direct interpolation between the sp(2) and the sp(3) o rbital configurations. In order to check the validity of the proposed interatomic potential we study by molecular dynamics (MD) carbon struc tures (diamond and graphite) around the equilibrium and finally, the d ynamic behaviour of a vacancy and an interstitial are also studied.
