Abstract

A detailed study of SiN (N=2-14) clusters has been performed through molecular dynamics (MD) simulation and the method of steepest descent quench (SDQ) with the Stillinger-Weber three-body potential. The approach is intrinsically a finite-temperature method which investigates all underlying mechanically stable structures visited by the system in the equilibrium state. Results indicate that the magic numbers, relatively stable clusters SiN (N=4,6,10), are determined by the topology and energetics of high energy bound structures rather than the structure and ground state energies at zero temperature.
