MOLECULAR-DYNAMICS SIMULATION OF GALLIUM MICROCLUSTERS

We have investigated the energetics and the structural stability of gallium microclusters including 3–7 atoms. A molecular-dynamics technique is employed in the simulation. The potential energy function used in the calculations includes two- and three-body interactions which are represented by Lennard-Jones and Axilrod-Teller type functions, respectively. It was found that the planar configurations are energetically more favorable for all the clusters studied.
