摘　　要：量子阱红外探测器受到温度、压强等多种因素的影响,本文主要从温度方面进行了研究。在文献[2]的基础上,进一步推导了超晶格中热应变与温度的关系;结合量子阱红外探测器的能级公式以及波长与能级差的关系式,定量地分析了温度变化对量子阱红外探测器探测峰值波长的影响。Quantum well infrared photo-detector was influenced by many factors such as temperature,pressure and so on.This paper makes a study on the influence of temperature mainly.Based on the paper [2],we derive the realitionship between the thermal strain and temperature in superlattice.Then combining energy level formula of quantum well infrared photo-detector with the relational expression of wavelength and energy level difference,we do quantitative analysis about the influence on detect peak wavelength of quantum well infrared photo-detector from tempereature.
