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

我们的项目侧重于原子尺度缺陷的体性质，超越平均场概念，描述真实的空间结构。我们将研究由单一金属杂质在金属宿主系统（例如Ag in Cu）以及金属纳米结构中引起的局部态密度的改变。随着纳米尺寸的减小，点缺陷对纳米结构的影响越来越重要，我们将分析限制对杂质电子性质的影响。扫描探针技术的最新发展为研究金属体系体缺陷开辟了一条新的实验途径。在平行的理论进展允许这样的系统建模，包括真实的带结构的主体材料。

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.
