Equipment for controlling nucleation and tailoring the size of solution-grown single crystals

Abstract: An improved version of the known temperature difference (T) technique of crystallization from solution is presented. A Peltier device was used to control the local temperature of nucleation, dissolution and growth in order to reduce typically occurring delay times in the nucleation process within a given sample tube and to tailor the size of the single crystals to be obtained.
