Dynamic crystallization in II–VI compounds synthesis from the vapour phase has been discussed. The method consists in the displacement of the growth zone by the predetermined change of the evaporation temperatures of the initial elements at constant flows of the transport gas. It leads to uniform distribution of grown crystals in the crystallization region and to the increase of the size and of the yield of crystals. Dynamic crystallization makes it possible to control the photoelectrical properties of the crystals and to increase the yield of the crystals with the required photosensitivity by changing the rate and the direction of the displacement of the growth zone.
