“…[116] Soon after the pioneering work on 2D BP transistors in 2014, [30] the band structure of BP was theoretically examined with the thickness ranging from bulk to monolayer. [33,34] The theory shows that bulk BP is a direct-gap semiconductor with a gap size of ≈0.3 eV, which is consistent with previous experimental values. The conduction band minimum (CBM) and valence band maximum (VBM) are both located at the Z point of the 3D Brillouin zone, while for the mono and fewlayer cases, the CBM and VBM are both shifted to point Γ of the 2D Brillouin zone, and the bandgap increases with a decreasing thickness.…”

“…[30] BP has a direct bandgap that exhibits a strong layer dependence, ranging from 0.3 eV (bulk) to 1.7 eV (monolayer). [31][32][33][34] It covers a broad frequency range from visible to mid-IR, filling up the gap between the most popular graphene and TMDCs. Moreover, the bandgap can be further tuned by strain [31,[35][36][37][38][39][40] and electric fields, [41][42][43][44] and even fully closed with a semiconductor-to-metal transition.…”

In the fast growing 2D materials family, anisotropic 2D materials, with their intrinsic in‐plane anisotropy, exhibit a great potential in optoelectronics. One such typical material is black phosphorus (BP), with a layer‐dependent and highly tunable bandgap. Such intrinsic anisotropy adds a new degree of freedom to the excitation, detection, and control of light. Particularly, hyperbolic plasmons with hyperbolic q‐space dispersion are predicted to exist in BP films, where highly directional propagating polaritons with divergent densities of states are hosted. Combined with a tunable electronic structure, such natural hyperbolic surfaces may enable a series of exotic applications in nanophotonics. Herein, the anisotropic optical properties and plasmons (especially hyperbolic plasmons) of BP are discussed. In addition, other possible 2D material candidates (especially anisotropic layered semimetals) for hyperbolic plasmons are examined. This review may stimulate further research interest in anisotropic 2D materials and fully unleash their potential in flatland photonics.

“…[147] It is worth noting that BP has a direct bandgap that varies with the number of layers, and its regulation range is from 0.3 to 2 eV. [19,[148][149][150] Its tunable bandgap range makes up for the bandgap vacancy of the previous semiconductor in the range of 0-1 V and has a good application prospect in the field of infrared and infrared detection. In summary, 2D materials have excellent electron mobility, an adjustable bandgap range with layer number variation, a wide light absorption wavelength, and a good light absorption performance.…”

“…The 2D materials not only can be separated from the bulk materials but also can be stacked together as needed to form a new structure, which is called a vertical heterojunction, [150,[172][173][174][175][176] as shown in Figure 1a. This artificial structure greatly enriches the application of 2D materials and facilitates the manufacture of artificial materials with excellent properties that do not exist in nature.…”

Self‐powered photodetectors are considered as a new type of photodetectors enabling self‐powered photodetection without external power. The excellent photoresponsivity, fast photoresponse rate, low dark current, and large light on/off ratio of these photodetectors have attracted wide interest among scholars. 2D materials are widely used in self‐powered photodetectors due to their excellent optical and electrical properties, unique 2D structures, and their capabilities to exhibit excellent photodetection performance. According to the self‐driving mechanism of 2D material‐based self‐powered photodetectors, they are divided into three categories: p–n junction photodetectors, Schottky junction photodetectors, and photoelectrochemical photodetectors. From these three perspectives, the research progress of 2D material‐based self‐powered photodetectors is summarized in detail here. Research reports indicate that 2D material‐based self‐powered photodetectors have excellent self‐powered photoresponse behavior, good light on/off characteristics, and wideband spectral response ranges. The excellent photoresponse performance of 2D material‐based self‐powered photodetectors facilitates their potential applications in the field of optoelectronic devices. In particular, self‐powered photodetectors have great potential as novel emerging self‐driven optoelectronic devices. Finally, directions for the further development of 2D material‐based self‐powered photodetectors are anticipated.

We systematically examined the effects of number‐of‐layer, pressure, and temperature on the bond length and energy, Debye temperature, atomic cohesive energy, and binding energy density for layered black phosphorus using bond–phonon–photon spectrometric methods. We clarified the following: (1) atomic under‐coordination shortens and stiffens the PP bond, which raises the B2g and Ag2 phonon frequency and widens the bandgap, (2) bond thermal elongation and weakening soften all phonon modes, and (3) bond mechanical compression has the opposite effect of heating on phonon frequency relaxation. The phonon and photon energy depends on the bond length and energy, which determines the relevant elasticity and thermal stability of layered structure. More broadly, the approaches and findings of this work provide both insight into and efficient tools for further exploration of unusual behaviors of other two‐dimensional substance.
