摘要
The growth of a supercritical nucleus from a diffusion field is studied numerically using a phase-field model. This represents growth of a crystal with small or vanishing anisotropy. We find three-dimensional cooperating multiplets instead of dendrites, in analogy to the doublons found previously in two dimensions. Tripler structures in particular appear to be the building blocks of the resulting morphology under conditions of free growth in three dimensions.
