New publication on grain boundaries in periodic and aperiodic crystals composed of patchy colloids
Using a Phase Field Crystal approach we have studied the behavior of grain boundaries in periodic and aperiodic crystals that are composed of patchy colloids. In case of periodic structures we find that the energy cost of a grain boundary is hardly affected by the preferred binding angles of the patchy particles. For quasicrystals we observe that the dislocations at the boundary recombine due to phasonic rearrangements.
