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> Dongqiong Chen, Hairong Wang, Rujie Li, Gongrong Deng Copyright (c) 2026 Author(s) https://ojs.bbwpublisher.com/index.php/JERA/article/view/13678 Wed, 04 Mar 2026 15:43:43 +0800
