It is shown in the present work that copper additives influence substantially the growth of Ga crystals from a melt which is expressed in different ways, depending on the impurity concentration. With rising copper concentrations we observed a substantial retarding in the growth rates as compared with deformed pure Ga crystals, and a change of the mechanism of growth. The results can be explained by a rejection of the impurity by the growing crystal which causes retarding of the growth and with the impurity inclusion like CuGa 2 particles, which gives rise to dislocations, intersecting the growing faces.
