Towards Cluster-Assembled Materials of True Monodispersity in Size and Chemical Environment: Synthesis, Dynamics and Activity

Abstract

This project by the Physical Chemistry group at TUM focused on the surface dynamics of size-selected clusters, studied with local Scanning Probe Microscopy methods. To this purpose, special fast STM techniques for the detection of the cluster dynamics, by imaging (FastSTM) and by tracking(cluster Tracking), have been implemented that were never used before for the study of size-selected clusters. This implementation can now routinely be used and has been applied for first investigations of surface reactions and cluster diffusion. In parallel to these local, microscopy studies, integral studies at ambient pressures have been performed to obtain a systematic insight into cluster ripening control. All the results obtained so far are given in the following summary and are listed in detail at the end (point P1 to P10).
