Geometric frustration in small colloidal clusters

Malins, Alex; Williams, Stephen; Eggers, Jens; Tanaka, Hajime; Royall, C. Patrick

Description

We study the structure of clusters in a model colloidal system with competing interactions using Brownian dynamics simulations. A short-ranged attraction drives clustering, while a weak, long-ranged repulsion is used to model electrostatic charging in experimental systems. The former is treated with a short-ranged Morse attractive interaction, the latter with a repulsive Yukawa interaction. We consider the yield of clusters of specific structure as a function of the strength of the...[Show more]
