Melt growth of high-resistivity CdZnTe crystals by controlling Cd over-pressures

Growth and Characterization of CZT Crystals by the Vertical Bridgman Method for X-Ray Detector Applications

“…The origin of the contamination of iron in our crystals is not clear yet. Actually, it was recently shown that impurities like iron or copper could efficiently diffuse through quartz at high temperature [13].…”

A method of promoting single crystal yield during melt growth of semiconductors by directional solidification

“…The technique was implemented to the directional solidification process of Cd 0.80 Zn 0.20 Te crystals, previously reported in Ref. [4], by adding a solenoid AC vibrator, which was bound to the growth ampoule, with a frequency of 60 Hz and an adjustable magnitude. The high-frequency shaking of the ampoule causes local inhomogeneity in the supercooled melt, which promotes the nucleation in the melt and, consequently, a small section of solid, usually single or double grain, was formed at the growth tip which grows continuously throughout most of the ingot length.…”

Growth and Characterization of CdZnTe Bulk Crystals Grown by Temperature Gradient Solution Growth

“…One of the most viable crystal growth methods is the traveling heater method (THM) [5,6], which can grow CdZnTe crystals with good quality but relative high cost and low yield. Other techniques such as low-pressure or high-pressure Bridgman require a higher growth temperature which introduces the difficulty for crystal growth and influences the material purity [7,8].…”
