Argon physisorption as structural probe for endohedrally doped silicon clusters.
We report on an element-dependent critical size for argon physisorption at 80 K on transition-metal-doped silicon clusters. Argon does not attach to elemental silicon clusters but only to surface-located transition-metal atoms. Thus physisorption provides structural information. Specifically, the minimal cluster size for the formation of endohedral singly metal-doped silicon cages has been dete...
متن کاملStructural Identification of Doped Silicon Clusters
In this chapter we review recent research on the structural identification of isolated doped silicon clusters by combining state-of-the-art experiments and computational modelling using the density functional theory formalism. The experimental techniques include chemical probe mass spectrometric methods, infrared action spectroscopy, photoelectron spectroscopy, and x-ray absorption spectroscopy...
متن کاملStructural identification of caged vanadium doped silicon clusters.
The geometry of cationic silicon clusters doped with vanadium, Si(n)V(+) (n=12-16), is investigated by using infrared multiple photon dissociation of the corresponding rare gas complexes in combination with ab initio calculations. It is shown that the clusters are endohedral cages, and evidence is provided that Si(16)V(+) is a fluxional system with a symmetric Frank-Kasper geometry.
متن کاملPredicting structural models for silicon clusters
This article introduces an efficient method to generate structural models for medium-sized silicon clusters. Geometrical information obtained from previous investigations of small clusters is initially sorted and then introduced into our predictor algorithm in order to generate structural models for large clusters. The method predicts geometries whose binding energies are close (95%) to the cor...
متن کاملPhotoelectron spectroscopy as a structural probe of intermediate size clusters.
We examine the utility of photoelectron spectroscopy (PES) as a structural probe of Si(n) (-) in the n=20-26 size range by determining isomers and associated photoelectron spectra from first principles calculations. Across the entire size range, we consistently obtain a good agreement between the theory and experiment [Hoffmann et al., Eur. Phys. J. D 16, 9 (2001)]. We find that PES can almost ...
