Abstract
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.

## Abstract The rate of growth of crystals from a melt containing the tetrasolvate of calcium nitrate with dimethylsulphoxide was measured in dependence on the supercooling (ฮ__T__ = 1โ46ยฐC) and the results were compared with the system containing the tetrahydrate of calcium nitrate. It was conclud
In this paper the effect of the growth temperature fluctuation, for instance, the transient furnace temperature variation due to a short-term electric power supply interruption on BBO crystal growth was investigated based on the theory of temperature wave transmitting in melt and the boundary layer
