“…Moreover, the electronic properties of graphene/talc vdW heterostructure could be further tuned by elementally doping (e.g., Al and Fe) in talc. More recently, Singla et al [215] introduced a significant magnetic moment into graphene/MoS 2 heterostructure by absorbing Cr atom onto the graphene or MoS 2 surface. The magnetism is induced by the interactions between Cr atom (Cr-3D state) with C atom (C-2p state) and S atom (S-3p state), which is important for the advances of nanomagnetism.…”

Abstract2D van der Waals (vdW) heterostructures are receiving increasing research attention due to the theoretically amazing properties and unprecedented application potential. However, the as‐synthesized heterostructures are generally underperforming due to the weak interlayer coupling, which inspires the researchers to find ways to modulate the interlayer coupling and properties, realizing the tailored performance for actual applications. There have been a lot of publications regarding the controllable regulation of the structures and properties of 2D vdW heterostructures in the past few years, while a review work summarizing the current advances is not yet available, though it is significant. This paper conducts a state‐of‐the‐art review regarding the current research progress of performance modulation of vdW heterostructures by different techniques. First, the general synthesis methods of vdW heterostructures are summarized. Then, different performance modulation techniques, that is, mechanical‐based, external fields‐assisted, and particle beam irradiation‐based methods, are discussed and compared in detail. Some of the newly proposed concepts are described. Thereafter, applications of vdW heterostructures with tailored properties are reviewed for the application prospects of the topic around this area. Moreover, the future research challenges and prospects are discussed, aiming at triggering more research interest and device applications around this topic.

“…The plane-wave density functional theory (DFT) 48 package CASTEP 49 was used to obtain a deeper understanding of the optical properties of the title compound. The exchange–correlation potential 50 was treated by the Perdew–Burke–Ernzerhof (PBE) method in the generalized gradient approximation (GGA) and interactions between the ionic cores and electrons were described by norm-conserving pseudopotential (NCP).…”

“…To better describe the exchange–correlation effects of localized electrons, a hybrid functional (HSE06) was used for the electronic structure and linear optical properties calculations. For static χ (2) coefficients, the length-gauge formalism is used, , which has been proved in calculating the second-order susceptibility. , The DFT method has been demonstrated to be an effective method to calculate the electronic structure of materials. − …”

The unity of structure-property design and practical synthesis is a key to develop nonlinear optical (NLO) materials. However, many designed structures are hard to get because of the incapability of controlling the arrangement of structural motifs. After careful synthesis, we successfully obtained a new NLO crystal with expected properties, KWO3F, which features a long-range anion-ordered while directed parallel arrangement of [WO5F] d0 transition metal fluorooxo-functional (d0 [TMOF]) motifs. This arrangement is vital to achieve a strong second-harmonic generation (SHG) response, which is proved by dipole moment analyses and theoretical calculations. Remarkably, KWO3F possesses a strong phase-matching SHG response (3 × KDP), high thermal stability (stable up to 350 °C in air), a large laser damage threshold (LDT, 129.7 MW/cm2), a wide transparent window (0.5–10 μm), and a suitable birefringence (0.088 @ 1064 nm). Our research demonstrated that the introduction of the NLO-active d0 [TMOF] motif is an effective strategy to design new potential NLO materials.
