1. A method of growing a cadmium zinc telluride (CdZnTe) crystal, the method comprising:
providing a crucible including a solid CdZnTe source;
forming a Te-rich Cd—Zn—Te melt on the solid CdZnTe source, wherein the Te-rich Cd—Zn—Te melt floats on the solid CdZnTe source;
positioning a CdZnTe seed crystal in physical contact with the Te-rich Cd—Zn—Te melt; and
growing the CdZnTe crystal from the Te-rich Cd—Zn—Te melt.
