Characterization of Different Growth Regimes on Prepatterned Surfaces — Fabian Lied¹, •Tanja Mues¹, Wenchong Wang², Lifeng Chi², and Andreas Heuer¹ — ¹Institut für Physikalische Chemie, Westfälische Wilhelms-Universität Münster — ²Physikalisches Institut, Westfälische Wilhelms-Universität Münster

Molecule deposition on a prepatterned substrate is a recently developed technique to generate structures of organic molecules on surfaces via self-organization. For the case of prepatterned stripes the time-resolved process of structure formation is studied via Lattice Monte Carlo simulations. By systematic variation of the interaction strength three distinct growth regimes can be identified: localized growth, bulge formation and cluster formation. All three growth regimes can be recovered in the experiment when choosing appropriate organic molecules. Some key microscopic observables, reflecting the properties of the structure formation, display a non-monotonous dependence on the interaction strength.
