Abstract: We study ion condensation onto a patterned surface of alternating charges.The competition between self-energy and ion-surface interactions leads to theformation of ionic crystalline structures at low temperatures. We considerdifferent arrangements of underlying ionic crystals, including single ionadsorption, as well as the formation of dipoles at the interface betweencharged domains. Molecular dynamic simulation illustrates existence of singleand mixed phases. Our results contribute to understanding pattern recognition,and molecular separation and synthesis near patterned surfaces.
