    摘要:

    应用半导体非平衡载流子连续性方程模拟了PbSe光电导红外探测器参数对光电响应的影响,实验研制了小规模像元的x-y寻址型PbSe光电导焦平面阵列(FPA)探测器,像元尺寸为500μm×500μm,像元间距为500μm。实验表征了PbSe FPA探测器像元的光电响应性能,有效像元率达到了100%。500K温度黑体辐射和3.0V偏压下像元的黑体响应率的范围是70~146mA/W,平均响应率和平均探测率分别达到了110mA/W和5.5×10^9cmHz^(1/2) W^(-1)。像元的噪声等效温差(NETD)范围是15~81mK,平均噪声等效温差为32mK。使用中波红外成像装置,初步演示了PbSe FPA探测器对350~450℃热辐射目标的红外成像。为后续研制高密度像元PbSe FPA探测器奠定了基础。

    Abstract:

    The influence of the parameters of PbSe photoconductive infrared detector on the photoelectric response was simulated by the continuity equation of semiconductor non-equilibrium carriers. A small-scale pixel x-y addressable PbSe photoconductive focal plane array (FPA) detector was developed experimentally. The pixel size was 500μm×500μm, and the pixel pitch was 500μm. The photoelectric response performance of the pixels of the PbSe FPA detector was experimentally characterized, and the effective pixel rate reached 100%. Under 500K temperature blackbody radiation and 3.0V bias voltage, the average responsivity and detectivity reached 110mA/W and 5.5×10^9 cmHz1/2W-1, respectively. The noise equivalent temperature difference (NETD) of the pixels ranged from 15 to 81mK, and the average noise equivalent temperature difference was 32mK. Using a mid-wavelength infrared imaging device, the infrared thermal imaging of the PbSe FPA detector on the thermal radiation target of 350~450℃ was preliminarily demonstrated. This work lays the foundation for the subsequent development of high-density pixel PbSe FPA detectors.
