Abstract: | Experiments were carried out to calculate by defining equations the distribution coefficient of zinc during the crystallization of GaP from the nonstoichiometric gallium melt. The TGS technique was applied to grow the crystals. Zinc detection was performed by the use of the radionuclide Zn65 as a tracer. The distribution coefficient being of the order of 0.1 is dependent upon temperature and concentration. These relations are demonstrated by plots and discussed with special respect to the literature data. |
