Abstract: The method for purposefully creating aperiodic radial impurity structures and controlling the shape of their spatial profiles in dilute alloys is presented. That is derived based on an analytical approach supported by the results of numerical calculations.

Keywords: unsteady directional controlled solidification, mobile impurities, aperiodic impurity profiles.
