Cadmium Telluride \ Cadmium Zinc Telluride – semiconductors directly converting radiation into electrical signals. Compare to others have such advantages as:
•Higher sensitivity and performance —> lower radiation dose
•Higher spatial and energy resolution —> finer and more detailed image
•Work at room temperature —> lightweight and portable
CdTe \ CdZnTe (CZT) single crystals:
– homogeneity of structure along the ingot with diameter\length – up to 75mm.
– crystallinity – up to 95 %
– light density of dislocations – 5×103 /сm2
– light density of Te inclusions with the size less than 10 mm – 103 /сm3
