<p>This research aims to enhance the operating temperature of mid-infrared InAsSb XBn detectors (~4.5 μm cutoff) through specific device architecture. Measurements performed under front-side illumination without an antireflection coating showed that at 290 K, the quantum efficiency was 34% for nBn devices compared to 45% for pBn devices. The nBn and pBn devices displayed distinct performance metrics at 290 K under a 500-mV reverse bias. The nBn devices recorded a dark current density of 0.348 A/cm² and a peak specific detectivity of 8.24×10⁸ cm‧Hz^1/2/W, whereas the pBn devices demonstrated improved characteristics with values of 0.536 A/cm² and 5.92×10⁹ cm‧Hz^1/2/W, respectively. The results indicate that these XBn structured barrier photodetectors exhibit excellent performance and demonstrate significant potential for near-room temperature applications.</p>
