Abstract: Quasielastic laser light-scattering measurements on the b and a faces of a Salol crystal growth into the melt revealed simultaneous lateral translational dynamics on the crystal surface and slow relaxational dynamics in a thin boundary layer of melt adjacent to the crystal. The slow relaxational dynamics were also observed when the crystal was melting. Analysis of the translational dynamics shows that crystal growth is mediated by highly polygonized screw dislocations. Several mechanisms which can be considered to explain the boundary layer dynamics are discussed. However, a consistent physical model to explain the slow relaxational dynamics has not yet been achieved.
