In pursuit of new optical properties, different materials and particle morphologies have been investigated in detail. Combining multiple of these building block types promises novel properties with respect to the single use thereof. Due to the nature of combinatorics, introducing more than a single building block leads to an exponential increase in parameter space, unable to be explored by established linearly scaling fabrication methods.

In an innovative approach, heterogeneous single particle lines of single-crystalline Ag and Au spheres are manufactured in a massive parallel approach by stochastic confinement assembly. By assembling billions of particles in one step, millions of combinations are generated. These ensembles are then studied in detail by electron energy loss spectroscopy (EELS) to reveal their plasmonic properties and to gain insight into heterogeneous coupling efficiencies.
