We aim to combine doping and surface modification of silicon clusters to tune their stability and functionality, i.e. the optical properties. This sub-project focuses on the spectroscopic investigation of the geometric and electronic structures of doped and surface modified silicon clusters in the gas-phase. We will apply vibrational spectroscopy for the investigation of the structural properties and anion photoelectron spectroscopy for obtaining insights into the electronic structures. In combination with theory we aim to achieve an understanding for the interplay of modification of the electronic and geometrical structures upon doping and chemical surface alteration.

我们的目标是结合掺杂和硅簇的表面改性来调整它们的稳定性和功能，即光学性质。这个子项目的重点是在气相中掺杂和表面修饰硅簇的几何和电子结构的光谱研究。我们将应用振动谱法研究其结构性质，应用阴离子光电子谱法研究其电子结构。结合理论，我们的目标是实现对掺杂和化学表面改变的电子和几何结构的修饰的相互作用的理解。
