TECHNOLOGY – CdTe X-ray detector
CdTe (Cadmium Telluride) is compound semiconductor formed from Cadmium and Tellurium. Bias voltage is applied to the electrodes which are formed on the both end of high resistive CdTe wafer. Electrical current scarcely flows when radiation is not irradiated due to the high electric resistivity; however, when radiation such as X-ray and γ- ray are exposed to CdTe detector, they are absorbed in CdTe and electron-hole pairs are generated in CdTe. These electrons and holes are drifted to anode and cathode electrode, respectively, by the internal electric field.
As mentioned above, radiation is absorbed in CdTe single crystal and obtained as electrical signals; this is the operation principle of CdTe radiation detector.
