Research on two-dimensional (2D) materials has been explosively increasing in last seventeen years in varying subjects including condensed matter physics, electronic engineering, materials science, and chemistry since the mechanical exfoliation of graphene in 2004. Starting from graphene, 2D materials now have become a big family with numerous members and diverse categories. The unique structural features and physicochemical properties of 2D materials make them one class of the most appealing candidates for a wide range of potential applications.In particular, we have seen some major breakthroughs made in the field of 2D materials in last five years not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing forward commercialisation. In this review, we provide a critical summary on the recent progress made in the field of 2D materials with a particular focus on last five years. After a brief background 物理化学学报 Acta Phys. -Chim. Sin. 2021, 37 (12), 2108017 (3 of 151) introduction, we first discuss the major synthetic methods for 2D materials, including the mechanical exfoliation, liquid exfoliation, vapor phase deposition, and wet-chemical synthesis as well as phase engineering of 2D materials belonging to the field of phase engineering of nanomaterials (PEN). We then introduce the superconducting/optical/magnetic properties and chirality of 2D materials along with newly emerging magic angle 2D superlattices. Following that, the promising applications of 2D materials in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially. Thereafter, we present the theoretic calculations and simulations of 2D materials. Finally, after concluding the current progress, we provide some personal discussions on the existing challenges and future outlooks in this rapidly developing field.

“…Thus, the most effective method for obtaining the exciton ground state involves computing the q-dependent BSE spectra. 54 In that case, we expect that f r would have even lower values, although still surpassing those obtained within the standard SLME.…”

“…It is important to point out that the presence of an indirect gap could lead to lower energy dark excitons that lead to non-radiative decay. Thus, the most effective method for obtaining the exciton ground state involves computing the q -dependent BSE spectra . In that case, we expect that f r would have even lower values, although still surpassing those obtained within the standard SLME.…”

Transition metal dichalcogenides (TMDCs) have garnered significant interest in optoelectronics, owing to their scalability and thickness-dependent electrical and optical properties. In particular, thin films of TMDCs can be used in photovoltaic devices. In this work, we employ ab initio many-body perturbation theory within the G 0 W 0 -BSE approach to accurately compute the optoelectronic properties of thin films of 2H-TMDCs composed of Mo, W, S, and Se. Subsequently, we evaluate their photovoltaic performance, including exciton recombination effects, and show that this is a key ingredient. We obtain efficiencies of up to 29% for a 200 nm thick film of WSe 2 , thus providing an upper limit. We also include other phenomenological recombination mechanisms that could be present in the current samples. This slightly reduces efficiencies, indicating that even with current synthesis technologies, there is still potential for further enhancement of TMDCs' performance in photovoltaic applications.

“…Various researchers have explored the electronic and optical properties of the PdS 2 and PdSe 2 monolayers, as well as the Janus PdSSe structure. 25,26 It has been found that these are semiconductor 2D materials with relatively large intrinsic band gaps. Many 2D metal oxides have been investigated theoretically or synthesized experimentally, 27,28 and there are the questions of whether the PdO 2 monolayer will be stable and what properties does this 2D material hold?…”
