Abstract

A diffuse interface theory of nucleation proposed recently for vapor condensation and crystal nucleation is compared with experiments and field-theoretical models of nucleation. Without adjustable parameters the theory gives an improved description of condensation experiments on non-polar and weakly polar substances. Cluster dynamics calculations are performed for homogeneous and heterogeneous crystal nucleation. Experiments on homogeneously nucleating oxide glasses indicate that a temperature-independent interface thickness is a reasonable assumption for even deep undercoolings. This offers a unique possibility for distinguishing homogeneous and bulk heterogeneous nucleation processes.
