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.
