Crystal growth at externally imposed nucleation clusters Idea: impose a cluster of fixed colloidal particles (e.g. by optical tweezer) Does this cluster act as a nucleation seed for further crystal growth? cf: homogeneous nucleation: the cluster occurs by thermal fl fluctuations, t ti here h we prescribe ib them th How does nucleation depend p on cluster size and shape? p (S (S. van Teeffelen Teeffelen, C.N.
