Linear and Nonlinear Optical Properties of Small Silicon Clusters
Abstract
Electronic contributions to the optical properties of small silicon clusters are examined. Geometries and the electronic structures of the clusters are established using the tight-binding model, and linear as well as nonlinear polarizabilities of conjecture for hyperpolarizabilities is shown to be violated in the frequency-degenerate case, which is of practical importance. The nonlinear polarizabilities are found to depend primarily on the symmetry of the cluster and prove to be high for the low symmetry clusters. Possible experiments and applications are discussed. Keywords: Small silicon clusters, Optical properties, Linear and nonlinear, Tight-binding model, One-electron density matrix, Hyperpolarizability.
