“…This is a situation frequently encountered for colloidal systems where the interparticle spacing is of the order of micrometres. The surface structure can then be realized either by chemical etching or other lithographic techniques [23,24] or by fixed colloidal spheres on a substrate [25][26][27][28][29][30][31][32][33][34]. Even a periodic wall pattern by many fixed colloidal spheres can be realized.…”

The physics of wetting phenomena at structured surfaces by crystalline layers as investigated by theory, computer simulation and experiments is reviewed. Both realizations on the molecular scale and more mesoscopic realizations in colloidal models systems are included. We explore how a crystalline wall pattern affects the wetting by a crystalline phase in the context of a simple hard sphere model relevant for sterically stabilized colloids. We further discuss decoration lattices generated by adsorption of colloidal particles on stripepatterned substrates. For molecular systems, the influence of a rough and preplated surface on triple-point wetting of hydrogen is calculated. Finally, we present data for fluid layering in primitive model simulations of charged colloids near neutral walls.

The equilibrium structure of decoration lattices composed of colloidal particles adsorbed on periodic stripe-patterned substrates is calculated as a function of the stripe width and separation and for different interparticle interactions. Due to a competition of length scales, a wealth of different stable decoration lattices occurs such as triangular, quadratic, rhombic, kitelike, and sheared honeycomb lattices, triangular slices as well as triangle superlattices. This is of relevance for constructing templates that enforce crystal growth of unusual solid structures.
