Abstract:

Our overall goal is to establish the groundwork for using clusters as the building blocks of new materials with tailored properties that are beneficial to the AFOSR. Our continuing program is composed of two interrelated themes the first comprises the investigation of fundamental physical and chemical properties of cluster building blocks in isolation, while the second involves the study of cluster deposition and assembly, including optical and chemical characterization of the formed materials. The ability to tune the pertinent properties of matter would facilitate the design of devices that could behave ideally in a specific application. Our objectives are outlined as follows 1. Explore the electronic and geometric structure of clusters to enable the design of stable motifs for use in high energy-density materials and nanocatalysis. 2. Characterize dynamical processes to allow the precise control of building block reactivity on the atomic scale. 3. Extend the formalism for describing the interactions of clusters in rarefied environments to build a methodology for treating deposited clusters. 4. Examine the intra and inter cluster length scale interactions of deposited clusters to determine how the properties of the nanoscale material emerge.
