Quasi-one-dimensional (Q1D) semiconductor materials, such as carbon nanotubes, SbSI, MP15 (M = Li, Na, K), and selenium and tellurium nanowires, show amazing potential for applications in future nanoelectronic and optoelectronic devices. However, intricate chirality in the structure of carbon nanotubes limits their applications. Also, the performance of MP15 in optoelectronics has yet to be extensively explored. One new Q1D semiconductor material, fibrous phosphorus (FP), has recently received attention because its raw material is less toxic. However, the ability to characterize FP by phase identification is limited in the assessment of micro/nano-thickness, such as exfibrated FP. So, identifying a precise Raman spectrum will allow for much better characterization. Here, a sufficiently sharp Raman spectrum of FP was obtained and analyzed. Moreover, we demonstrated that high-quality, few-layer FP fibers with thicknesses as low as 5.55 nm can be produced by liquid-phase exfibration under ambient conditions in solvents. More importantly, an optoelectronic detector based on a single FP fiber field-effect-transistor configuration was investigated. A rise time as short as about 40 ms was obtained for the FP transistors, illustrating the potential of FP single bundle crystals as a new one-dimensional material for optoelectronic device applications.

纤维状磷的液体扩散和光电器件。
准一维（Q1D）半导体材料，例如碳纳米管，SbSI，MP15（M = Li，Na，K）以及硒和碲纳米线，在未来的纳米电子和光电设备中显示出惊人的潜力。然而，碳纳米管结构中复杂的手性限制了它们的应用。同样，MP15在光电领域的性能还有待广泛探索。一种新型的Q1D半导体材料，纤维磷（FP），由于其毒性较小而受到关注。但是，通过相鉴定来表征FP的能力在评估微观/纳米厚度（如游离FP）方面受到限制。因此，确定精确的拉曼光谱将允许更好的表征。在此，获得并分析了FP的足够清晰的拉曼光谱。而且，我们证明了在环境条件下在溶剂中通过液相剥离可以生产出厚度低至5.55 nm的高质量，少层FP纤维。更重要的是，研究了基于单个FP光纤场效应晶体管配置的光电探测器。FP晶体管的上升时间短至约40 ms，这说明了FP单束晶体作为光电器件新的一维材料的潜力。
