The fundamental understanding of the structural, optical and electrical properties of size-controlled Si nanocrystals is the scope of this project in order to explain the recently evolved questions. In terms of the optical properties this relates to the interaction of neighbouring NCs as well as a deeper understanding of excitonic migration. Therefore, the in-plane TEM investigations have to be continued to obtain a direct comparison of structural and optical data. Special attention is paid to the clarification of the mechanisms of multiple exciton generation (MEG, or SSQC for space separated quantum cutting). Based on our longtime experience with Si nanocrystals and our excellent experimental basis we want to achieve groundbreaking results in the framework of this continuation proposal in the understanding of fundamental optical and electronic properties of indirect quantum dots.

对尺寸可控硅纳米晶体的结构、光学和电学性质的基本理解是本项目的范围，以解释最近演变的问题。在光学性质方面，这涉及到相邻NC之间的相互作用以及对激子迁移的更深层次的理解。因此，必须继续进行面内的透射电子显微镜研究，以获得结构和光学数据的直接比较。特别注意阐明多激子产生的机制(MEG，或空间分离量子切割的SSQC)。基于我们对硅纳米晶体的长期经验和我们良好的实验基础，我们希望在这个延续方案的框架内，在理解间接量子点的基本光学和电学性质方面取得开创性的成果。
