Abstract

Flexible shortwave infrared detectors play a crucial role in wearable devices, bioimaging, automatic control, etc. Commercial shortwave infrared detectors face challenges in achieving flexibility due to the high fabrication temperature and rigid material properties. Herein, we develop a high-performance flexible Te_0.7Se_0.3 photodetector, resulting from the unique 1D crystal structure and small elastic modulus of Te–Se alloying. The flexible photodetector exhibits a broad-spectrum response ranging from 365 to 1650 nm, a fast response time of 6 μs, a broad linear dynamic range of 76 dB, and a specific detectivity of 4.8 × 10¹⁰ Jones at room temperature. The responsivity of the flexible detector remains at 93% of its initial value after bending with a small curvature of 3 mm. Based on the optimized flexible detector, we demonstrate its application in shortwave infrared imaging. These results showcase the great potential of Te_0.7Se_0.3 photodetectors for flexible electronics.

用于柔性短波红外光探测器和成像的一维晶体结构 Te-Se 合金

柔性短波红外探测器在可穿戴设备、生物成像、自动控制等领域发挥着重要作用。商用短波红外探测器在实现柔性方面面临着高制造温度和刚性材料特性的挑战。在本文中，我们开发了一种高性能柔性 Te0.7Se0.3 光电探测器，其独特的一维晶体结构和 Te-Se 合金的小弹性模量使之成为可能。这种柔性光电探测器具有从 365 纳米到 1650 纳米的宽光谱响应、6 μs 的快速响应时间、76 dB 的宽线性动态范围以及室温下 4.8 × 1010 琼斯的比探测率。柔性探测器在以 3 毫米的小曲率弯曲后，其响应率仍保持在初始值的 93%。基于优化的柔性探测器，我们展示了它在短波红外成像中的应用。这些结果展示了 Te0.7Se0.3 光电探测器在柔性电子领域的巨大潜力。
