CZT Pixilated Detector

CZT Pixilated Detector

In contrast to indirect semiconductor detectors, CZT provides ‘direct’ solid-state technology. The CZT semiconductor is a pixilated array with an effective Z of 50 and a density of 5.8 g/cm3. Gamma rays enter the CZT semiconductor detector and are directly converted to electron hole pairs. These charges (electrons and holes) then drift towards positive and negative electrodes, respectively, inducing electrical output signals.If you have any special requirements, contact us and the R&D engineer can design it.
