低温目标红外辐射的灵敏探测和成像在航天和深空探测中具有重要的应用价值.300 K以下低温目标的辐射强度很弱,辐射特征波长位于中远红外区.阻挡杂质带红外探测器是中远红外探测器中重要的一员,具有覆盖波段宽、灵敏度高、暗电流低、抗辐射性能高等优点,能够胜任空间技术和天文探测在中远红外波段探测的苛刻要求.本文以红外天文探测对红外探测器的应用需求作为出发点,主要就国内外红外天文学、红外天文探测器发展概况,阻挡杂质带红外探测器发展历史及其材料、器件结构等方面做了简要综述,并简明扼要地介绍了阻挡杂质带探测器的器件物理模型.
Sensitive detection and imaging of cryogenic target infrared radiation have important application value in space and deep space exploration.The radiation intensity of cryogenic target below 300 K is very weak and the characteristic wavelength of radiation is located in the far-infrared region. An important member of the detector has the advantages of wide coverage band, high sensitivity, low dark current and high radiation resistance, and is capable of performing the demanding requirements of space technology and astronomical detection in the COSCO infrared band.In this paper, infrared astronomical detection of infrared detection As a starting point, this paper briefly reviews the development of infrared astronomy and infrared astronomy detectors at home and abroad, the history of the development of barrier infrared detectors and their materials and device structures, and briefly introduces the barrier impurities Physical model of the device with detector.
