CdTe (CT) \ CdZnTe (CZT)

–  semiconductors directly converting radiation into electrical signals. Compare to others have such advantages as: 

Higher sensitivity               à lower radiation dose

Higher spatial and energy resolution    à finer and more detailed image

Work at room temperature à lightweight and portable

 

used in the following applications:

- medical imaging, tomography, fluorography

rapid screening for security and customs inspections

- Non Destructive Testing and technical diagnostics

- nuclear materials control, spectrometry

- X-ray fluorescence analysis

- infrared detectors for thermo and night vision equipments 



 Single crystals  CdTe \ CdZnTe :

- homogeneity of structure along the ingot with diameter up to 75mm \ 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
