“…[47] At present, 2D materials obtained using this method can achieve single-layer thicknesses. [38,48] Furthermore, the monolayer superposition of any material can be obtained, so that 2D vdWhs are available through the stacking of vdWfs. In this specific preparation process, the single-layer 2D material is first obtained by stripping the tape, and then transferring the single-layer 2D material to different substrates, such as quartz and silica/silicon.…”

2D van der Waals heterojunctions (vdWhs) are a novel type of metamaterial that are flexible, adjustable, and easy to assemble. Using weak van der Waals forces (vdWfs), layered 2D materials can stack freely to form vdWhs with atomic level flat interfaces. By using different 2D materials and specific stacking methods, their unique properties can be organically combined, to exhibit more abundant optical properties. In fact, nanophotonic devices based on 2D vdWhs have developed rapidly and made significant progress. Therefore, the main progress of 2D vdWhs nanophotonic devices in recent years, including the preparation methods of 2D vdWhs and the performance improvements of various nanophotonic devices, is reviewed. Lastly, the prospects of 2D vdWhs nanophotonic devices are discussed.

“…[19] The interlayer distance between phosphorene nanosheets is around 5.3 Å with the lattice constant of a ¼ 3.31 Å, b ¼ 10.47 Å, and c ¼ 4.37 Å. [20,21] These unique crystal structure characteristics and physical properties make BP a promising 2D material for application in different fields of science and technology such as energy storage devices, [18,[22][23][24] catalysts, [25,26] field-effect transistors, [27,28] sensors, [29,30] optoelectronics, [31,32] and biomedical devices. [33,34] The properties and the device performance of phosphorene largely depend on its thickness and preparation method.…”

Black phosphorus (BP) as a rising star among 2D materials has attracted attention for a wide range of applications due to its fascinating properties. The key point for the real application of phosphorene depends on its exfoliation technique to produce high‐quality nanosheets. In recent years, tremendous efforts have been made in the preparation and energy storage application of phosphorene and phosphorene‐based hybrid electrodes. Herein, the state‐of‐the‐art liquid‐based exfoliation and characterization of phosphorene fabricated by sonication, anodic and cathodic electrochemical exfoliation, and bipolar electrochemical exfoliation in diverse solutions and conditions are discussed. In addition, the electrochemical properties and storage mechanism of phosphorene‐based electrodes for rechargeable batteries and supercapacitors are discussed. Finally, the challenges and opportunities of phosphorene nanosheets in terms of exfoliation and energy storage applications are addressed.

Moreover, BP has a 0.3-1.5 eV thicknessdependent direct bandgap [27,28] ranging from the mid-infrared to visible region, supplying the bandgap interspace between monolayer graphene (below 0.2 eV) and TMDCs (1-2.5 eV). [3,29] With high carrier mobility (≈10 3 cm 2 V −1 s −1), [4,30] BP has also been viewed as a promising candidate for the fabrication of field-effect transistors and photodetectors. [11,31-34] While BP is being considered for long-term applications owing to its high performance, its terrible preservation in air hampers practical application. After exposing mechanically exfoliated flakes to oxygen or water vapor under ambient conditions, rapid degradation takes place in a very short timescale (minutes), [35,36] greatly impacting the benign nature of the material. Until now, there have been many reports on quantum dots and nanosheets in BP dispersions through the liquidphase exfoliation technique. [10,37-40] Nevertheless, it is difficult to guarantee the stable value of relevant tests because of the metastable BP products that are completely in an organic solvent environment and of indefinitely small size. Another way to improve the antioxidant capacity of BP is the doping approach. Particularly, doping engineering [41] including substitution doping, intercalation doping, surface charge transfer doping, and electrostatic carrier doping, has been demonstrated to be an easy but pragmatic technique for the amelioration of the physicochemical properties of BP. [41] Substitution doping with S, Se, and Te provides extra freedom with controllable characteristics. [42-45] However, the doping function of these elements on nonlinear optical properties [46-50] or ultrafast photonic applications [51-55] has been minimally explored so far. Selenium-doped BP (Se-BP), synthesized by the chemical vapor transport method, is reported to exhibit some intriguing characteristics. [44,56,57] Previous studies have found that Se doping renders BP enhanced long-term air stability and an optical response ascribed to the regulation of intrinsic carrier density. [56] Under a doping range of 0-1.6%, Se atoms effectively reduce the probability of phosphine oxidation by decreasing the conduction band close to or even lower than the redox potential of O 2 /O , 2 − which allows BP to achieve air stability that lasts for several days. [44] The high-quality crystal structure of Se-BP coincides with that of BP, which is convenient for dissociation and peeling off, resulting in good bipolar electrical
