Abstract: Optimum geometries of silicon clusters up to 71 atoms have been found by a recently developed Monte Carlo based global optimization method. Structural properties of these clusters have been investigated and the results have been compared with available results obtained by other methods. Radial distribution of atoms of Si71 have been compared with the silicon crystal structure.

Keywords: Silicon clusters, Monte Carlo optimization, empirical potential energy functions
