Abstract
(English)
A technique for the determination of the partial pres- sures of Cd and Te􏰇 vapors in equilibrium with cadmium zinc tel- luride (CdZnTe) crystals has been developed. The technique has shown a large range of applicability. First of all, the technique can be used for the in-situ monitoring of the partial vapor pressures in the case of technological relevant processes, such as material pu- rification and crystal growth. Moreover, the technique is applied to the characterization of the composition of CdZnTe crystals with a sensitivity of at least two orders of magnitude more than previ- ously reported techniques.
