Modeling of metal cluster growth on hard surfaces — Sven-Jannik Wöhnert1,2, •Matthias Schwartzkopf2, Stephan V. Roth2, and Christian Schroer2 — 1Universität Hamburg — 2Deutsches Elektronen-Synchrotron (DESY)
Sputter deposition is one high-throughput method to install patterned nanostructures on surfaces with high deposition rates. Grazing incidence small-angle X-ray (GISAXS) scattering nowadays delivers a wealth of information during in-situ processes and real-time observations. The geometric model of [1] then allows to extract general cluster parameters to describe the growth of metal clusters on surfaces.
The geometric model of [1] then allows to substract general cluster parameters to describe the growth of metal clusters on surfaces. To gain insight into the specific evolution of cluster growth, we investigated cluster formation during sputter deposition at different temperatures on various hard surfaces in order to discover dependencies and relations on atomic level.
Therefore, we present a phenomenological Monte-Carlo simulation comparing cluster parameters with the results of the GISAXS measurements. We provide information about the dependencies of surface diffusion, nucleation and cluster interaction on the cluster evolution.
