Liquid Encapsulated Flux Growth of ZnSe Single Crystals from Se Solvent

Abstract
In order to grow ZnSe single crystals free from twins, a solution growth method from Se solvent was developed. The evaporation of Se solvent was effectively suppressed by utilizing a liquid encapsulant of molten fluorides and a gas over pressure. The liquidus curve of the Se-rich side in the Zn-Se system was established. Crystals were grown at a temperature of about 1200°C, where the solubility of ZnSe to Se solvent is high. The crystals were free from twins.
