Indium antimonide (InSb) crystal has became a hot spot in the field of semiconductor materials due to its unique physicochemical properties and excellent process compatibility since it is discovered. In recent years, as its application prospect in the field of infrared detection, it is widely concerned and valued by many research institution all over the world, and the technology has developed rapidly. At present, InSb crystal is the first choice for the preparation of high-performance medium wave infrared detector, which has great application prospect and commercial demand. The rapid development of infrared detector based on InSb crystal have greatly improved the performance of the infrared system and it promoted the infrared technology wide application in military and civil fields. This paper mainly introduce the properties of InSb crystal and summarize the research progress of InSb crystal at home and abroad, as well as its application in the field of infrared detection. Finally, the prospect and trend of its development is prospected.
