摘要
The photoabsorption spectra of silicon cluster cations Si-n(+), for n=2-13, are deduced from the analysis of the photodissociation spectra of xenon-silicon cluster cation complexes Sin+Xe. The spectra are measured for photon wavelengths between 290 and 700 mn (1.78 to 4.28 eV) for nless than or equal to6 and between 230 and 700 nm (1.78 to 5.40 eV) for n>6. The electronic structures and photoabsorption spectra of the Si-n(+) clusters are calculated within the framework of the density-functional theory, starting from optimized geometries published in the literature. Several explanations are given for the discrepancies between the experimental results and the simulations. In particular, we address the problem of the reliability of the photodissociation technique with an aim to deduce the photoabsorption spectra in the case of very small nonmetallic clusters.
