“…In such a manner, one can predict 2D FM materials with Tc over room temperature to develop high-performance spintronic devices. Zheng et al identified an ideal FM Fe3P monolayer, whose Tc reaches ~420 K 1757 . Furthermore, it was reported that a new 2D pentagon-based monolayer, penta-MnN2 displays a high Tc of 913 K that can be further improved to 956 K by biaxial tensile strain 1758 .…”

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.

Rectification of Spin Currents in a Metal/Insulator/Metal Heterostructure

Rectification of spin currents is investigated theoretically in a normal‐metal/ferromagnetic‐insulator/normal‐metal heterostructure. The ferromagnetic insulator is assumed to have an anisotropic parameter of Δ > 1, and thus it is gapped. In the presence of a magnetic field along the z‐direction, the ground state becomes the one with all spins pointing upward (in the z‐direction). When a spin‐up polarized current is incident from the left metal, it is suppressed due to spin blockade; however, the spin‐down polarized current can pass through the insulator easily. Thus rectification of spin currents can be realized and it is found that the rectification coefficient can be up to ≈10 (or even higher) in the limit of low temperature or large energy gap. It can be further improved when the spin system is asymmetrically coupled with the metals. The results could be useful in spintronics based on magnetic insulators.

“…The calculations were based on density functional theory [22,23] in which the ground state properties of a many-electron system are determined by an electron density with three spatial coordinates instead of N electrons with 3N spatial coordinates many-body problem, and performed using the plane-wave pseudopotential Vienna ab initio Simulation Package [24][25][26], which is a well-tested code and has been successfully used to calculate a great variety of materials [17][18][19][27][28][29][30]. The generalized gradient approximation [31] was used for the exchange-correlation functional, which was formulated by Perdew, Burke, and Ernzerhof (GGA-PBE).…”

The stability, physical properties, and electronic structures of Cr(NCN)2 were studied using density functional theory with explicit electronic correlation (GGA+U). The calculated results indicate that Cr(NCN)2 is a ferromagnetic and half-metal, both thermodynamically and elastically stable. A comparative study on the electronic structures of Cr(NCN)2 and CrO2 shows that the Cr atoms in both compounds are in one crystallographically equivalent site, with an ideal 4+ valence state. In CrO2, the Cr atoms at the corner and center sites have different magnetic moments and orbital occupancies, moreover, there is a large difference between the intra- (12.1 meV) and inter-chain (31.2 meV) magnetic couplings, which is significantly weakened by C atoms in Cr(NCN)2.
