Abstract
The polarizabilities of Si clusters with 9 to 28 atoms are calculated using a density functional cluster method. The atomic geometries are based on those carefully optimized by energy minimization. The polarizability shows fairly irregular variation with cluster size, but all calculated values are higher than the polarizability of a dielectric sphere with bulk dielectric constant and equivalent volume.Keywords
