Size-Selected ClusterBeam Source
Deposition of Size-Selected Atomic Clusters
Teer Coatings has developed a new instrument for the gas-phase synthesis and deposition of nano-clusters. The clusters generated by magnetron sputtering and gas condensation can be size-selected with a mass resolution > 100, and beam currents up to 1nA are available. Single and multi-element clusters can now be created.
Nano-Cluster Characteristics
The clusters can be elemental or alloys, synthesised from multiple elemental sources or alloy targets. Clusters can be “size-selected” via a dynamic lateral mass filter with beam currents up to 1nA, and sized from single atoms to >10nm. If a broader cluster size range is acceptable in a given application, clusters can be extracted before the mass filter, at enhanced rates. They can be deposited on a range of vacuum-compatible substrates, including powders as well as planar materials. The gas-phase approach results in ultra-clean clusters, free of ligands and by-products inherent in the conventional chemical synthesis of similar materials.
CB10 ClusterBeam Features

- Potential for co-deposition (i.e. nano-clusters and matrix materials)
- Controlled deposition energy
- Industry compatible with different substrate materials and forms, including powders/particulates
- Single element, alloy and multiple sources
- Upper mass selection limit exceeds Cu60,000 atoms/cluster
- Much higher rates possible for partially size-selected clusters (>1µA)
- High effective bean currents for size-selected, ionised nano-clusters (up to 1nA)
