为适应遥感、遥测及精确制导技术的发展,我们已研制出一定性能的CdS/HgCdTe(0.3～0.5μm/3～5μm)、Si/InSb(0.3～1.05μm/3～5μm)、Si/HgCdTe(0.3～1.05μm/3～5μm)、HgCdTe/LiTaO_3(3～5μm/8～14μm)、HgCdTe/HgCdTe(3～5μm/8～14μm)等多种双色红外探测器。其中HgCdTe/HgCdTe(3～5μm/8～14μm)光导双色探测器的峰值探测率D~*(5.1,980,1)=2.1×10~(10)cmHz~(1/2)/W,D~*(9.8,980,1)=8.1×10~9cmHz~(1/2)/W, 峰值响应率R(5.1,980,1)=1.3×10~4V/W,R(9.8,980,1)=373V/W。文中介绍了双色探测器的设计、结构、制备及器件的性能水平。
In order to adapt to the development of remote sensing, telemetry and precision guidance technology, we have developed CdS / HgCdTe (0.3-0.5μm / 3-5μm), Si / InSb (0.3-1.05μm / 3-5μm) (0.3 ~ 1.05μm / 3 ~ 5μm), HgCdTe / LiTaO_3 (3 ~ 5μm / 8 ~ 14μm) and HgCdTe / HgCdTe (3-5μm / 8 ~ 14μm). The peak detection rate of HgCdTe / HgCdTe (3 ~ 5μm / 8 ~ 14μm) photoconductors was 2.1 × 10 ~ (10) cmHz ~ (1/2) / W The peak response rate R (5.1,980,1) = 1.3 × 10 -4 V / W, R (9.8,980, 1) = 8.1 × 10 -9 cm 2 / (1/2) 1) = 373V / W. The paper introduces the design, structure, preparation and performance level of two-color detector.
