摘要
锗锡具有吸收系数高、直接带隙发光效率高、可用CVD生长、器件制备与硅工艺兼容等优势,是非常重要的硅基光电子材料。锗锡CVD生长技术及其探测器在理论意义和长远的军民用价值,受到欧美军事部门及政府机构的广泛资助。综述了锗锡CVD生长技术的研究历史、生长难点与发展趋势。基于CVD技术生长的锗锡,并结合锗锡探测器的发展史,探讨了高性能锗锡探测器在短波红外(SWIR)、中波红外(MWIR)和长波红外(LWIR)波段应用所面临的关键科学问题,强调了锗锡单光子雪崩光电二极管(SPAD)的优势及其在量子计算、激光雷达和无人驾驶等领域的应用前景。
GeSn has the advantages of high absorption coefficient,high direct bandgap light emission efficiency,able to grow by CVD,and compatible with Si CMOS technology,indicating it is a vital Si-based optoelectronic material.Theoretical significance,and long-term military and civilian value are being widely funded by the military departments and government agencies in the Western country.This paper reviews the research history,growth difficulties,and development trend of GeSn CVD growth technology.Based on the GeSn grown by CVD and combine with the GeSn detectors history,critical scientific problems faced by the application of high performance GeSn detector in short wavelength infrared(SWIR),medium wavelength infrared(MWIR),and long wavelength infrared(LWIR)bands are discussed.Besides,advantages of GeSn single photon avalanche photodiodes(SPAD)and its application prospects in quantum computing,lidar,and driver-less are emphasized.
