Cluster-ion bombardment of thin films
Proceedings, annual meeting, Electron Microscopy Society of America, 1984Energetic cluster ion impact on solid surfaces can be used to deposit large quantities of kinetic energy in small assemblies of atoms in the surface. Extremely high transient pressures and increases in the density of surface atoms are produced by these impact processes. Significant alteration of surface structure is expected.

Charged clusters in thin film growth
International Materials Reviews, 2004Abstract A cauliflower structure is a granular film composed of spherical particles similar in size, each with numerous nanoscale nodules on its surface. The structure is produced during certain chemical vapour deposition (CVD) processes for diamond and silicon thin film growth.

Thin-ended clusters in percolation in
Advances in Applied Probability, 2023AbstractConsider Bernoulli bond percolation on a graph nicely embedded in hyperbolic space $\mathbb{H}^d$ in such a way that it admits a transitive action by isometries of $\mathbb{H}^d$ . Let $p_{\text{a}}$ be the supremum of all percolation parameters such that no point at infinity of $\mathbb{H}^d$ lies in the boundary of the cluster of a ...

Cluster ion assisted thin film formation
AIP Conference Proceedings, 1997A new thin films formation technique using gas-cluster ion beams is demonstrated. Oxygen cluster ion beams are utilized to grow oxide films. We have found that high quality SiO2 films of up to 11 nm thick can be formed on Si substrate surfaces at room temperature by direct oxidation using O2 and CO2 cluster ion beams at acceleration voltages of less ...

Cluster-beam deposition for high-quality thin films
Physical Review A, 1989Transmission electron microscopy studies have recently shown that low-energy cluster-beam deposition allows the formation of higher-quality films compared with the classical molecular-beam deposition. This work presents preliminary results obtained with antimony deposits.

Thinning of Cluster Processes: Convergence of Sums of Thinned Point Processes
Mathematics of Operations Research, 1984This is a study of the convergence in distribution of sums of dependent point processes that are becoming uniformly sparse due to a thinning operation. Under this operation, each point process is randomly deleted or retained depending on its structure, and when a process is retained, each of its points is deleted or retained depending on its location ...

Cluster assembled thin films of covalent materials
Zeitschrift für Physik D Atoms, Molecules and Clusters, 1997Cluster assembled thin films of covalent materials are studied by Raman spectroscopy. The main properties are discussed in terms of frustration through several examples (carbon, silicon, and boron nitride). Some applications such as luminescence are discussed.

Wall clusters in thin soft ferromagnetic configurations
Journal of Applied Physics, 1981The wall cluster, which is a new concept in ferromagnetic domain theory, is introduced as a tool for getting a grip on the development of domain structures. A wall cluster consists of an arbitrary number of walls, which have a common intersection line.

Nanostructured thin films prepared from cluster beams
Surface and Coatings Technology, 2011Abstract Plasma polymer nanostructures were prepared by cluster beam deposition. The nanocluster source assembled in our laboratory is implementing a 2 in. planar magnetron operated in radio-frequency mode and follows the Haberland concept. Clusters were deposited on glass or silicon substrates without mass separation in order to get high deposition ...
