Abstract

In recent years, industrial production and national defense modernization have put forward higher requirements for the performance of sensors. The research and development of high-performance new sensors has attracted more and more attention. For gas sensing, the development of high performance and low-cost medium-wave infrared detectors at high operating temperature or even room temperature is one of the main development directions in the future. In recent years, HgCdTe, quantum well and antimonide infrared detectors have been the research hotspots of mid-wave infrared detectors. They have their own characteristics in device physics and device performance, and have their own advantages in gas detection applications. This paper summarizes the advantages and disadvantages of three kinds of mid-wave infrared detectors, and introduces the research status and development.
