Abstract

The static electric dipole polarizability of small Si clusters was investigated. The methods used were based on different techniques to calculate the polarizability. Thus, some methods used the higher-order finite-difference pseudopotential, while others have employed an all-electron approach. The results show that B3PW91 combined with pseudo-potential and a suitable basis set was a very powerful method to reproduce the polarizabilities of Sin clusters with size range n=1-8.
