量子阱红外探测器(QWIP)是一种对红外辐射信息进行高灵敏度感应的光电转换器件,温度是影响其性能的一个参数.文章以超晶格量子阱发射与干涉电子态理论和吸收波长公式为依据,通过计算温度对势阱、势垒宽度和势垒高度的影响,得出量子阱红外探测器峰值波长与温度的变化关系.发现:当温度升高时,探测峰值发生改变,其中有两处峰值发生红移,一处发生蓝移.这对精确分析红外辐射携带信息和制作非制冷量子阱红外探测器提供了理论指导.
Quantum Well Infrared Detector (QWIP) is a kind of optoelectronic transducer with high sensitivity to infrared radiation information, and temperature is a parameter that affects its performance.In this paper, quantum well trap quantum well emission and interference electron states theory and absorption wavelength formula , The relationship between the peak wavelength and the temperature of the quantum well IR detector is obtained by calculating the effect of temperature on the potential well, the barrier width and the barrier height. It is found that when the temperature rises, the peak value of the probe changes. The redshift of the two peaks and the blue shift of the two peaks provide the theoretical guidance for the accurate analysis of infrared radiation carrying information and making uncooled quantum well infrared detectors.
