II类超晶格红外探测器技术国内外进展

简单归纳整理了德国、美国(CQD、JPL、QmagiQ、NRL、Teledyne和Raytheon)、瑞典(IRnova)、以色列SCD和日本等国外主要机构的II类超晶格研究成果以及国内的发展现状。美国VISTA计划的成功实施和技术突破进一步加速推动了II类超晶格红外探测技术从理论走向现实。虽然目前及今后较长时间内HgCdTe技术仍然是主流,但是II类超晶格技术在整体系统性能和成本上可以挑战HgCdTe,II类超晶格技术将在红外应用领域全方位替代HgCdTe技术的优势已经越来越清晰。与国外相比,国内II类超晶格技术的发展已经具有一些技术基础,但距离产业化推广应用还有一定的差距,可以借鉴国外的先进理论和技术经验并结合具体实际工艺逐步取得突破。

Advances in type II superlattice infrared detectortechnology at home and abroad

This paper briefly summarizes the research results of type II superlattices from Germany,the United States (CQD,JPL,QmagiQ,NRL,Teledyne and Raytheon),Sweden (IRnova),Israel SCD and Japan,as well as the domestic development status.The successful implementation of the VISTA program in the United States and technological breakthroughs further accelerate the development of type II superlattice infrared detection technology from theory to reality.Although HgCdTe technology is still the mainstream at present and for a long time to come,type II superlattice technology can challenge HgCdTe in terms of overall system performance and cost.The advantages of type II superlattice technology in replacing HgCdTe technology in the field of infrared application are becoming increasingly clear.Compared with foreign countries,domestic type II superlattice technology development has some technical basis,but there is still a certain gap from the industrialization promotion and application,we can learn from foreign advanced theory and technical experience and combine with the specific practical process to gradually make breakthroughs.
