Abstract
In a method of performing a solution growth of a ZnSe crystal using Se as a solvent and relying on the temperature difference technique, the growth is performed under the conditions that the vapor pressure of Zn which is lower than the vapor pressure of Se is applied, under controlled manner, to the solvent during the growth process, in which the value of the Zn vapor pressure is held constant at 7.2 atm. .+-.30%, whereby a ZnSe crystal having a good crystal perfection is obtained.
