摘要：

This paper presents the recent progress in the research of high operating temperature (HOT) mid -wave-length infrared (MWIR) HgCdTe focal plane arrays (FPAs) at Kunming Institute of Physics. By optimizing the structural parameters of mid-wavelength infrared HgCdTe detectors, a 640x512@15 & mu;m mid-wavelength infrared focal plane array (FPA) was fabricated based on high-quality in situ indium-doped HgCdTe film grown by liquid phase epitaxy (LPE) using arsenic-ion-implanted p-on-n planar junction device technology. The spectral response, device dark current, noise equivalent temperature difference (NETD), operability, and the distribution of defective pixels of the prepared p-on-n chip arrays at various operating temperatures were tested using a variable temperature Dewar. The test results demonstrate that the detector has the ability to operate at temperatures above 180 K.
