Two-dimensional clusters of colloidal tetramers via droplet emulsion templating

In this report, using a kinetic Monte Carlo simulation method we consider a hierarchical assembly of square-shape tetramers , constrained in a plane, via droplet evaporation. We found that colloidal tetramers undergo a structural transition from initial square-shape tetramers to diamond-like tetramers. A variety range of resulting clusters of square-shape tetramers belongs to a particular class of geometrical shape, namely polyiamonds, that are previously reported to the clusters of single colloids. However, due to geometrical constrained of tetramers, many novel structures can be observed. Considering potential applications of colloidal clusters in electronics, photonic materials, our result could provide an effective way to control the formation of complex colloidal cluster structures.
