Study on Morphological Evolution of Ag-nanostructured Films Prepared by Mass-selected Clusters| Chapter 4 | Newest Updates in Physical Science Research Vol. 12

 In terms of application, the fabrication of metal nanoclusters using a gas phase synthesis process and their deposition on a solid surface has various advantages. The morphological characteristics of films generated by mass- or size-selected silver nanoclusters on Si substrates were studied since the size of the deposited nanostructure can influence many properties of a thin film. A gas aggregation type magnetron-based nanocluster source is used to create the Ag-nanoclusters films, and a Quadrupole Mass Filter (QMF) is used to size-select the Ag-nanoclusters films. The film is deposited using a variety of cluster beams.current for a cluster size of roughly 4 nm diameter and a constant deposition time Atomic force microscopy (AFM) and scanning electron microscopy (SEM) are used to examine the morphology of the films (SEM). According to the findings, the nanostructured film is initially mono-dispersed for smaller cluster ion currents, but mound-like formations appear for higher ion currents. For the creation of mound-like structures, the impacts of surface diffusion and agglomerations of deposited clusters are explored. The elemental purity of the films under consideration is demonstrated by structural and composition studies.
