Abstract

Further progress has been made in the development of the Modified Vertical Bridgman method for the growth of CdZnTe crystals for fabrication of x-ray and gamma-ray detectors to operate at room temperature. Specifically, the diameter of the grown ingots has been increased from 2 to 3 inches. High quality, large volume (up to 6 in³) twin-free single crystals have been produced. Detectors fabricated with this material show sharp energy resolution and good uniformity.
