Abstract
High quality CdZnTe thick films were prepared on boron and gallium co-doped ZnO (BGZO) transparent conductive films by using close-spaced sublimation (CSS) method. Due to its high stability, hardness and similar thermal expansion coefficient with CdZnTe, BGZO films were also used to replace the traditional metal to form good ohmic contact with CdZnTe. CdZnTe thick film radiation detectors with BGZO/CdZnTe/BGZO structure were fabricated. The results showed a well response of the CdZnTe thick film detector (the energy resolution is about 25%) from a 60 KeV 241Am γ-source.
