The resulting size-dependent growth shapes are significantly different from equilibrium microcrystallites, and have a distribution of grain sizes different from isotropic theories. As an application of our results, we show that the persistence decay exponent depends on anisotropy and hence is nonuniversal.4 pages (revtex), 2 eps figuresStatistical MechanicsMaterials ScienceSoft Condensed Mattertext
