Colloidal Ordering on a 2D Quasicrystalline Substrate
Physical Review Letters
By using Monte Carlo simulations, we study the complex phase behavior of charged-stabilized colloidal particles in a two-dimensional substrate potential with quasicrystalline decagonal symmetry. In the regime where the strengths of the substrate and colloidal pair potential are comparable, we identify a novel and unexpected quasicrystalline phase with pure 20-fold bond order and a disordered structure without any apparent rotational symmetry. Furthermore, we demonstrate how phasonicdoi:10.1103/physrevlett.101.218302 pmid:19113456 fatcat:fo7dsvbk4zaohp7uvkzk2yxjle
