Atomic scale impurities in metallic nanoscale structures: A combined experimental and theoretical study

我们的项目重点是超越平均场的概念和描述的真实的空间结构的原子尺度缺陷的体积特性。我们将研究在金属宿主系统（例如，Ag在Cu中）以及金属纳米结构中由单个金属杂质诱导的局部态密度的修改。由于点缺陷对纳米结构的影响将变得越来越重要，随着尺寸的减小，我们将分析限制对杂质的电子性质的影响。扫描探针技术的发展为研究金属体系中的体缺陷开辟了一条新的实验途径。在平行的理论进展允许建模这样的系统，包括主体材料的真实的能带结构。

Our project focuses on bulk properties of atomic scale defects going beyond mean field concepts and describing the real space structure. We will study modification in the local density of states induced by single metallic impurities in a metallic host system (e.g. Ag in Cu) as well as in metallic nanostructures. As the impact of point defects on nanoscale structures will become more and more important with reduced size we will analyze the impact of confinement on the electronic properties of the impurities. Recent development in scanning probe techniques has opened a new experimental way to study bulk defects in metallic systems. In parallel theoretical progress allows modeling such systems including the real band structure of the host material.
