Calculated polarizabilities of small Si clusters
نویسندگان
چکیده
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.

Static Electric Dipole Polarizabilities of Na Clusters
The static electric dipole polarizability of NaN clusters with even N has been calculated in a collective, axially averaged and a three-dimensional, finite-field approach for 2 ≤ N ≤ 20, including the ionic structure of the clusters. The validity of a collective model for the static response of small systems is demonstrated. Our density functional calculations verify the trends and fine structu...

The electronic and structural properties of semiconductor clusters are examined using pseudopotentials and a real space method. Examples of this method are applied to predict the photoemission spectra, the vibrational modes, and the polarizabilities of Si and Ge clusters.
متن کاملAssessment of exchange-correlation functionals for the calculation of dynamical properties of small clusters in TDDFT
We present a detailed study of different exchange-correlation (xc) functionals in describing the dynamical properties of finite systems. For that purpose, we calculated the static polarizabilities, ionization potentials and optical absorption spectrum of four small clusters, Na2, Na4, SiH4 and Si2H6, using a real-space, real-time technique. The computed static polarizabilities and ionization po...
متن کاملMedium perturbations on the molecular polarizability calculated within a localized dipole interaction model
We have studied the medium effects on the frequency-dependent polarizability of water by separating the total polarizability of water clusters into polarizabilities of the individual water molecules. A classical frequency-dependent dipole–dipole interaction model based on classical electrostatics and an Unsöld dispersion formula has been used. It is shown that the model reproduces the polarizab...

The frequency dependent polarizabilities of closed-shell alkali metal clusters containing up to ten lithium, potassium, and rubidium atoms have been calculated using the linear complex polarization propagator approach in conjunction with Hartree–Fock and Kohn–Sham density functional theory. In combination with polarizabilities for C60 from a previous work [J. Chem. Phys. 123, 124312 (2005)], th...
