| dc.description | Polarizabilities of Ge$_n$ clusters with 2 to 25 atoms are calculated using coupled-perturbation Hartree-Fock (CPHF) and finite field (FF) method within density functional theory. The polarizabilities of the Ge$_n$ clusters increase rapidly in the size range of 2 to 5 atoms and then fluctuate around the bulk value. The polarizabilities are sensitively dependent on the cluster geometries and electronic structures. The large HOMO-LUMO gap may lead to the small polarizability. As compared with the compact structure and diamond structure, the prolate cluster structure corresponds to a larger polarizability. | |
