Abstract: By use of molecular-dynamics and simulated annealing technique, we have studied the structural properties of Sin cluster at zero and high temperature. The results are in good agreement with ab-initio calculations.

Key words: Si cluster, molecular-dynamics, empirical potential, simulated annealing
