Abstract

Silicon is very important in the modern electrical industry, for example for the production of solar cells. To improve their efficiency the newest generation of solar cells consists of nanostructures like quantum dots. Therefore studies about optical properties of silicon nanoclusters are of particular interest [1]. These characteristics for the smallest cluster Si$_{2}$, which is necessary for the formation of larger clusters, are not well established yet [1].\\ In this talk, experimental data and quantum chemical calculations on the absorption and dissociation properties of Si$_{2}^{+}$ are presented. The spectrum of Si$_{2}^{+}$ was obtained by photodissociation of mass-selected Si$_{2}^{+}$ cations in a tandem mass spectrometer, which are created in a laser vaporization source [2]. The experimental results are compared and discussed with theoretical results of TD-DFT calculations. Significantly, our optical spectrum provides the first spectroscopic information for this simple diatomic cation. \\ Literature: \\ [1] L.-Z. Zhao et al. J. Phys. Chem.
