Advances in Crystal Growth of CdTe-based Compound Semiconductors for Room Temperature Radiation Detectors
CdTe-based compound semiconductor materials have broad application prospects in the field of room-temperature radiation detection because of their wide band gaps,good photoelectric properties and electron transport performance.CdTe,CdZnTe,CdMnTe and CdMgTe single crystals have excellent carrier transport properties and are used as X-ray and γ-ray detectors at room temperature.The difficulties of crystal growth,such as strong ionic property and poor thermal conductivity of CdTe-based crystals,are discussed .The growth methods of CdTe-based crystals were introduced,and the latest research progress in the field of room temperaturer radiation detection was reviewed.Finally,the development direction of CdTe-based crystals was prospected,which provided more imagination space for the applications of CdTe-based compound semiconductor crystal materials.
