项目摘要

ABSTRACTProposal ID: 508239Title: NER: Measurement of the separation dependence of the dot-dot interactionPI: Ricardo S. DeccaThis proposal will characterize the interaction between two nanocrystals. These nanocrystals are made of CdSe, a semiconductor. Each one of the nanocrystals behave as an "artificial atom", where its properties can be controlled by changing its properties. In particular, the discrete energy levels that electrons can take in the nanocrystals are strongly affected by their size. This project will deal with how an "artificial molecule" forms, by studying the interaction of two such nanocrystals. Although these interactions have been studied either in ensembles of nanocrystals or between two nanocrystals fixed in space, the novelty of this work is mainly associated with the fact that the separation between the two nanocrystals can be varied and controlled. In this way the dependence of the interaction with respect to the separation can be investigated. This study is important to achieve a complete characterization of the nanoparticles, the effect of non-uniformities on their properties and on their interactions. This is, in turn, important for the implementation of these particles in more advanced systems, as fluorescent markers and even in potential quantum computers.

建议ID：508239标题：NER：点-点相互作用的分离依赖关系的测量PI：Ricardo S.Decca这个建议将表征两个纳米晶体之间的相互作用。这些纳米晶体是由半导体镉硒制成的。每一个纳米晶体都像一个“人造原子”，它的性质可以通过改变它的性质来控制。特别是，电子在纳米晶体中可以获得的离散能级受到它们大小的强烈影响。这个项目将通过研究两个这样的纳米晶体之间的相互作用来研究“人造分子”是如何形成的。虽然这些相互作用已经在纳米晶体系综或固定在空间中的两个纳米晶体之间进行了研究，但这项工作的新颖性主要与两个纳米晶体之间的分离可以改变和控制这一事实有关。通过这种方式，可以研究相互作用相对于分离的依赖性。这项研究对于实现对纳米粒子的完整表征、非均匀性对其性能的影响以及对其相互作用的影响具有重要意义。反过来，这对于在更先进的系统中实现这些粒子作为荧光标记，甚至在潜在的量子计算机中也是重要的。
