“…[ 32 ] In addition, UV photodetectors based on other 2D MPCs such as FePS 3 and MnPS 3 have been reported as well. [ 81,120 ] Remarkably, the negative and positive photocurrent in FePS 3 UV detectors can be switched by changing the bias voltage. [ 81 ] In addition, because of the robust stability and strong light absorption of 2D MPCs, exploring new type of photodetector based on MPCs is important.…”

2D layered phosphorous compounds (2D LPCs) have led to explosion of research interest in recent years. With the diversity of valence states of phosphorus, 2D LPCs exist in various material types and possess many novel physical and chemical properties. These properties, including widely adjustable range of bandgap, diverse electronic properties covering metal, semimetal, semiconductor and insulator, together with inherent magnetism and ferroelectricity at atomic level, render 2D LPCs greatly promising in the applications of electronics, spintronics, broad‐spectrum optoelectronics, high‐performance catalysts, and energy storage, etc. In this review, the recently research progress of 2D LPCs are presented in detail. First, the 2D LPCs are classified according to their elemental composition and the corresponding crystal structures are introduced, followed by their preparation methods. Then, the novel properties are summarized and the potential applications are discussed in detail. Finally, the conclusion and perspective of the promising 2D LPCs are discussed on the foundation of the latest research progress.

Transition‐Metal Phosphorus Trisulfides and its Vacancy Defects: Emergence of a New Class of Anode Material for Li‐Ion Batteries

In the search of suitable anode candidates with high specific capacity, favorable potential, and structural stability for lithium‐ion batteries (LIBs), transition‐metal phosphorus trisulfides (TMPS3) can be considered as one of the most promising alternatives to commercial graphite. Here, it was demonstrated that the limitations of commercial anode materials (i.e., low specific capacity, large volume change, and high lithium diffusion barrier as well as nucleation) can be circumvented by using TMPS3 monolayer surfaces. The study revealed that lithium binds strongly to TMPS3 monolayers (−2.31 eV) without any distortion of the surface, with Li@TMPS3 exhibiting enhanced stability compared with other 2D analogues (graphene, phosphorene, MXenes, transition‐metal sulfides and phosphides). The binding energy of lithium was overwhelmingly enhanced with vacancy defects. The vacancy‐mediated TMPS3 surfaces showed further amplification of Li binding energy from −2.03 to −2.32 eV and theoretical specific capacity of 441.65 to 484.34 mAh g−1 for MnPS3 surface. Most importantly, minimal change in volume (less than 2 %) after lithiation makes TMPS3 monolayers a very effective candidate for LIBs. Additionally, the ultralow lithium diffusion barrier (0.08 eV) compared with other existing commercial anode material proves the superiority of TMPS3.

“…Extensive investigation of Raman scattering and light emission in MnPS 3 and related systems reveals strong electron-phonon coupling of the even-symmetry modes as well as field-effect transistor behavior. 17,[40][41][42][43] Because trends in the oddsymmetry (ungerade) vibrational modes are crucial for uncovering local structure modifications, testing various parent and subgroup candidates, and developing higherlevel functionalities like ferroelectricity, 20,[44][45][46] bringing infrared spectroscopy to the field of few-and single-layer chalcogenides is an important step forward.…”

Near-field infrared spectroscopy of monolayer MnPS3

et al. 2019

We measured the near-field infrared response of MnPS3 in bulk, few-, and single-layer form and compared our findings with traditional far field vibrational spectroscopies, a symmetry analysis, and first principles lattice dynamics calculations. Trends in the Bu mode near 450 cm −1 are striking, with the disappearance of this structure in the thinnest sheets. Combined with the amplified response of the activated Ag mode and analysis of the Au + Bu features, we find that symmetry is unexpectedly increased in few-and single-sheet MnPS3 due to a restoration of the threefold axes of rotation. Monoclinicity in this system is therefore a consequence of the long-range stacking pattern and temperature rather than local structure.
