The main goal of this project is to provide a theoretical description of the mechanisms for charge transfer processes through single clusters on surfaces and energy transfer processes between clusters in a cluster array. In particular, we propose to perform: - Calculation of the current through clusters deposited on surfaces. Determination of the conductivity of the supported clusters. Study of the influence of the cluster-surface interaction, (e.g. deformation of the cluster, rearrangement of electronic levels, changes in the tunneling matrix elements) on the transport properties of the clusters. - Calculation of Förster coupling between clusters in a cluster array. Dynamical study of the energy flow for different cluster size distributions and geometric arrangements. Optimization of the energy transfer.

该项目的主要目标是提供表面上单个簇的电荷转移过程和簇阵列中簇之间的能量转移过程的理论描述，特别是，我们建议执行： - 计算通过簇的电流。确定支撑团簇的电导率，研究团簇-表面相互作用（例如团簇的变形、电子能级的重新排列、隧道矩阵元素的变化）对团簇传输特性的影响。簇。 - 簇阵列中簇之间的福斯特耦合的计算。不同簇尺寸分布和能量传输优化的能量流的动态研究。
