On the theoretical determination of the static dipole polarizability of intermediate size silicon clusters
MetadataShow full item record
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.
