摘要：

A molecular-dynamics study has been performed to investigate SiN clusters (N = 5 - 14, 26), using the three-body interaction potential of Lennard-Jones/Axilrod-Teller. Starting from the ground-state structures with increasing temperature there are changes between different solid-like structures as well as transitions from the solid-like to the liquid-like state to be observed. The melting temperature depends on the cluster size. The ''magic numbers'' 6 and 1 0 are to be observed not only at T = 0 K but also at higher temperatures as excellently stable.
