Abstract
Using quasi elastic light-scattering technique, a layer has been detected at the solid-liquid interface of a growing ice crystal. A diffusive process in this layer is rate-limiting for solidification under conditions close to thermodynamical equilibrium, as well as during free growth of a crystal into supercooled melt. Similar results have been obtained with salol, a substance which forms many facets during crystal growth from the melt. The macroscopic growth rates of ice and salol can be scaled using the diffusion constant measured by light scattering at the solid-liquid interface.
