Modified vertical bridgman growth of Cd1−xZnxTe detector grade crystal in a 4 inch EDG furnace

Year: 2009

Type: conference-paper

Abstract: Achieving a high yield of detector grade CdZnTe single crystals is one of the greatest challenges in CdZnTe crystal growth. Over 85, 3.5-4 inch long CdZnTe crystals were grown in a 43 zone modified low pressure Vertical Bridgman Electro-Dynamic Gradient (EDG) Freeze 3 in. Mellen Sunfire furnace. The diameter of the grown ingots has been increased using a new Electro-Dynamic Gradient (EDG) Freeze 4 in. Mellen Sunfire Platinum coil furnace to visualize the effects of increased ampoule diameter on the grain structure and spectroscopic properties of CdZnTe. The reproducibility of detector grade crystals using the 4 in. furnace is discussed and some properties of the fabricated detectors are presented.
