The aim of this project is to tailor the electronic and optical properties of silicon clusters by combining doping and surface modification. The ultimate goal is to arrive at a level of understanding where targeted control of these properties will become feasible. This requires a fundamental investigation of doped silicon clusters and their interaction with adsorbate molecules as well as surface passivation. In close collaboration with experimental and theoretical groups of the research unit we will address these questions across the visible through X-ray photon energy range by applying X-ray photoionization and UV photodissociation spectroscopy, resonant Raman spectroscopy, as well as photoluminescence spectroscopy. These techniques will yield detailed insight into the electronic and geometric properties of surface modified doped silicon clusters.

该项目的目的是通过掺杂和表面改性相结合来定制硅团簇的电子和光学性质。最终的目标是达到一个理解的水平，有针对性地控制这些属性将成为可行的。这就需要对掺杂硅团簇及其与吸附物分子的相互作用以及表面钝化进行基础研究。在与研究单位的实验和理论小组密切合作，我们将通过应用X射线光电离和紫外光解离光谱，共振拉曼光谱，以及光致发光光谱在可见光通过X射线光子能量范围内解决这些问题。这些技术将产生详细的洞察到表面改性的掺杂硅团簇的电子和几何性质。
