| Abstract: | Cadmium zinc telluride(CdZnTe)is an important Ⅱ-Ⅵ compound semiconductor.It is an ideal material for room temperature radiation detectors due to its excellent opto-electrical properties.However,defects such as Cd vacancies,precipitate/inclusion phases,impurities and dislocations inevitably exist in asgrowth CdZnTe crystals.These defects seriously influence the quality and opto-electrical performance of the fabricated devices.Therefore,the properties of as-grown crystals need to be improved by annealing.The main defects in CdZnTe were analysed in this paper.The research progress of annealing processes such as annealing temperature,annealing time,annealing atmosphere and annealing method on the crystal quality and detector performance of CdZnTe was particularly reviewed. |
