Abstract

As a type of layered van der Waals material, transition metal phosphorus trichalcogenide FePSe₃’s high carrier mobility and light absorption capability offering this p-type semiconductor promising utilization in broadband optoelectronics detection. Despite of the specific photoelectric response behavior of the FePSe₃-based solid-state photodetectors, the self-powering potential of the FePSe₃-based devices still remains unexplored. In this study, we harnessed the architecture of the photoelectrochemical photodetector and fabricated a FePSe₃-based device to investigate its photoelectric performance under different illumination and bias conditions. It was found that the device demonstrated a visible-near-infrared self-powering detection capability ranging from 400 to 800 nm, fast response speed, high sensitivity and outstanding cyclic stability. This research signifies the promising potential of FePSe₃ in the field of self-powered optoelectronics.

基于 FePSe3 的可见光-近红外自供电光电探测器

作为一种层状范德华材料，过渡金属磷三碲化物 FePSe3 的高载流子迁移率和光吸收能力使这种 p 型半导体在宽带光电检测领域大有可为。尽管基于 FePSe3 的固态光电探测器具有特殊的光电响应行为，但基于 FePSe3 的器件的自供电潜力仍有待开发。在本研究中，我们利用光电化学光电探测器的结构，制作了一个基于 FePSe3 的器件，研究其在不同光照和偏置条件下的光电性能。研究发现，该器件具有 400 纳米到 800 纳米的可见光-近红外自供电检测能力、快速响应速度、高灵敏度和出色的周期稳定性。这项研究表明，FePSe3 在自供电光电领域具有广阔的应用前景。
