红外光电探测器已经历了半个多世纪的发展,先后出现了机械扫描式单元及线列探测器和凝视型红外焦平面探测器两代探测器技术,并形成了一个庞大的红外探测器器件家族.近年来人们逐渐提出了以高探测率、大面阵、低成本、多光谱为技术特点的第三代红外探测器概念.锑化物红外探测材料以其具备的优越光电性能:量子效率高,暗电流小,微带带隙可调,均匀性高、成本低等,成为第三代红外焦平面探测器的最优选材料.本文回顾了近年来国内外第三代红外探测器材料与器件的研究发展历程,重点阐明了锑化物II类超晶格红外探测材料在技术上的优势及其国内外发展现状.通过分析个多个重点研究机构的技术发展历程,阐明了锑化物材料与器件研究的发展趋势,面临的挑战以及今后数年内该领域的研究重点.
Infrared photodetector has experienced more than half a century of development, has appeared in the mechanical scanning unit and line detector and staring infrared focal plane detector two generations of detector technology and the formation of a large infrared detector device Family.In recent years, people gradually put forward the concept of the third generation infrared detector with high detection rate, large area array, low cost and multi-spectrum as the technical characteristics.Anti-antimony infrared detection material with its superior optoelectronic properties: high quantum efficiency , Dark current is small, adjustable microstrip bandgap, high uniformity, low cost, become the third-generation infrared focal plane detector of the most preferred material.This paper reviews the third generation of infrared detectors in recent years, materials and devices And highlights the technical advantages of antimony II superlattice infrared detection materials and their development status at home and abroad.By analyzing the technical development history of a number of key research institutions and clarifying the antimony compound materials and devices The development trend of the research, the challenges it faces and the research priorities in this field in the next few years.
