Abstract

The influences of impurity on surface morphology and growth kinetics of tetragonal lysozyme crystals were studied. There was a significant difference in morphology of 2D islands on a {110} face when the impurities existed. Impurities significantly decreased the normal growth rates of both the {110} and {101} face. F-lysozyme decreased the normal growth rate of both the {110} face and {101} face. The values of kinetic coefficient of the steps, surface free energy, and ledge free energy of the step edge were determined.
