“…We conducted a comprehensive series of tests to ensure the optimal performance of the VPNS used in our experiments. Scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), and X-ray diffraction (XRD) (see Figure c,d) analyses revealed that the violet phosphorus and VPNS exhibited high quality. ,− The lattice spacing and intersecting angle both closely match those of the (110) and ( ) lattice planes in the crystallographic structure of violet phosphorus single crystals, as determined by single-crystal X-ray diffraction (XRD). Analogous to the XRD patterns, strong stretching vibration modes of [P9] cages at 293 cm –1 (S 1 [P9] ) and 353 cm –1 (S 2 [P9] ), the stretching mode of [P8] at 373 cm –1 (S 2 [P8] ), and the tangential stretching mode of [P9] along the tubular axis at 471 cm –1 ( T g ) were readily observed in violet phosphorus (Figure e).…”

As a second-order nonlinear optical phenomenon, the bulk photovoltaic (BPV) effect is expected to break through the Shockley− Queisser limit of thermodynamic photoelectron conversion and improve the energy conversion efficiency of photovoltaic cells. Here, we have successfully induced a strong flexo-photovoltaic (FPV) effect, a form of BPV effect, in strained violet phosphorene nanosheets (VPNS) by utilizing strain engineering at the h-BN nanoedge, which was first observed in nontransition metal dichalcogenide (TMD) systems. This BPV effect was found to originate from the disruption of inversion symmetry induced by uniaxial strain applied to VPNS at the h-BN nanoedge. We have revealed the intricate relationship between the bulk photovoltaic effect and strain gradients in VPNS through thickness-dependent photovoltaic response experiments. A bulk photovoltaic coefficient of up to 1.3 × 10 −3 V −1 and a polarization extinction ratio of 21.6 have been achieved by systematically optimizing the height of the h-BN nanoedge and the thickness of VPNS, surpassing those of reported TMD materials (typically less than 3). Our results have revealed the fundamental relationship between the FPV effect and the strain gradients in low-dimensional materials and inspired further exploration of optoelectronic phenomena in strain-gradient engineered materials.

Recently, 2D violet phosphorus (VP), a new kind of allotrope of phosphorus has attained significant attention owing to its remarkable electronic, optical, and magnetic characteristics. Tunable, large direct bandgap, high charge carrier mobility, and large optical absorption make it a potential candidate for realizing photoelectronic applications. VP demonstrates unique electronic structure, chemical stability, strong light‐matter interaction, and thermal stability that can be utilized for assembling intelligent photoelectronic devices. This review article provides comprehensive investigations of the latest synthesis techniques employed to develop the VP including its structural characterizations, stability, and degradation mechanisms. Furthermore, this review demonstrates the diverse applications of VP in optoelectronics, including photodetectors, polarization detection, imaging systems, neuromorphic optoelectronic devices, and many others. Finally, challenges and future research directions associated with the VP in terms of optoelectronics are discussed. Overall, as presented, the review offers an extensive study of VP, covering its synthesis, structural insights mechanisms, and applications in optoelectronics with the aim of stimulating further research and development in this growing field.
