Abstract: Stable valley-layer coupling, which can be against spin–orbit coupling (SOC), is of both fundamental and technological importance as it offers a design principle for 2D valleytronics however, a reliable mechanism to achieve the goal is missing. In this Letter, a general rule to design such valley-layer coupling is mapped out from symmetry analysis. The degenerate valleys with valley-contrasted layer physics and protected valley-layer coupling can be present in bilayer lattice, when special symmetry operations between layers depending on the inversion center are satisfied. Such valley-layer coupling and its stability against SOC are further revealed in a real material of MnF4 based on first-principles. The distinctive properties, such as optical selection of valley and electric polarization of interlayer excitons, are observed in such a unique system. Our results not only provide a feasible principle to design materials with stable valley-layer coupling but also greatly enrich the physics and broaden the scientific impact of 2D valleytronics.

Abstract: The recent emerged two‐dimensional (2D) ferroelectrics have attracted tremendous research interests due to their promising application in nonvolatile electronics devices. The reversible electric polarization of ferroelectrics from the off‐centered positive and negative surfaces can effectively lift the band states near Fermi level and modulate the charge distribution, which therefore play important roles for the controllable electronic/magnetic properties and chemical reactions. Here, based on the latest revealed 2D ferroelectrics, we reviewed the research progress of ferroelectric controlled physical properties and chemical reactions, including the effects of reversible polarization on magnetic and electronic behaviors, polarization dependent photocatalytic water splitting and gas adsorptions. The associated applications in electronics, sensors and energy conversion are also discussed. At last, the possible research directions of 2D ferroelectrics have also been proposed. The review is expected to inspire the research interests of 2D ferroelectrics in the practical applications.

Abstract: Toxic gas detection and capture are two important topics, which are highly related with human health and environments. Recently, theoretical simulations based on first‐principles calculations have suggested two‐dimensional (2D) materials to be as ideal candidates for gas sensing and capturing due to the large surface–volume ratio and reactive surface. Starting from graphene, which was firstly proposed for 2D gas sensing, the family currently has been extended to transition metal dichalcogenides, phosphorene, silicene, germanene, MXene, and so on. In this review, we give a comprehensive overview of recent progress in computational investigations of 2D gas sensing/capture materials. We then offer perspectives on possible directions for further fundamental exploration of gas sensor and caption based on 2D materials, which are expected to offer tremendous new opportunities for future research and development.

Abstract: We report on mechanical properties of blue phosphorus nanotubes (BluePNTs) from systematic molecular dynamics simulations, adopting a Stillinger-Weber potential with parameters determined by fitting to energetic and structural data from first-principles calculations. Our results corroborate the previously reported bending poison effect and size-dependent buckling behaviors. Under axial compression, current simulations predict a shell-to-column buckling mode transition for BluePNTs with increasing aspect ratios further compression of BluePNTs with large aspect ratios results in a column-to-shell buckling mode transition. Associated critical buckling strains can be described by the continuum mechanics theory. We also simulated buckling behavior of black phosphorus nanotubes (BlackPNTs) and found that the buckling modes of BluePNTs exhibit much less chirality dependence compared to BlackPNTs, stemming from subtle structural differences between these two closely related yet distinct systems. The present results offer insights into key structural and mechanical properties of BluePNTs for fundamental understanding and potential applications of this relatively new member of the large and erse nanotube family of materials.

Abstract: Efficient and selective CO 2 electroreduction into chemical fuels promises to alleviate environmental pollution and energy crisis, but it relies on catalysts with controllable product selectivity and reaction path. Here, by means of first-principles calculations, we identify six ferroelectric catalysts comprising transition-metal atoms anchored on In 2 Se 3 monolayer, whose catalytic performance can be controlled by ferroelectric switching based on adjusted d -band center and occupation of supported metal atoms. The polarization dependent activation allows effective control of the limiting potential of CO 2 reduction on TM@In 2 Se 3 (TM = Ni, Pd, Rh, Nb, and Re) as well as the reaction paths and final products on Nb@In 2 Se 3 and Re@In 2 Se 3 . Interestingly, the ferroelectric switching can even reactivate the stuck catalytic CO 2 reduction on Zr@In 2 Se 3 . The fairly low limiting potential and the unique ferroelectric controllable CO 2 catalytic performance on atomically dispersed transition-metals on In 2 Se 3 clearly distinguish them from traditional single atom catalysts, and open an avenue toward improving catalytic activity and selectivity for efficient and controllable electrochemical CO 2 reduction reaction.

Abstract: Recent years have seen the rising importance of interface stacking in determining the electronic properties of multilayer materials stemming from the interlayer coupling however, the stacking effects on exotic topological quantum orders largely remain to be explored. Here, we show by first-principles studies that bilayer Bi2Te3 host stacking is dependent on quantum spin Hall effects, with a topological phase transition induced by a change in the interlayer stacking pattern. The spin-filtered helical edge states are concomitantly switched on/off along with the changing interlayer stacking pattern. Since few-layer Bi2Te3 has already been experimentally synthesized, the present finding opens an avenue for exploring the fundamental mechanisms and the practical implications of the quantum phenomena associated with band topology in this versatile and intriguing 2D material.

Abstract: Janus two-dimensional (2D) materials, referring to the layers with different surfaces, have attracted intensive research interest due to the unique properties induced by symmetry breaking, and promising applications in energy conversion. Based on the successful experimental synthesis of Janus transition metal dichalcogenides (TMDC), here we present a review on their potential application in photocatalytic overall water splitting, from the perspectives of the latest theoretical and experimental progress. Four aspects which are related to photocatalytic reaction, including the adsorption of water molecules, utilization of sunlight, charge separation and transport, and surface chemical reactions have been discussed, and it is concluded that the Janus structures have better performances than symmetric TMDCs. At the end of this review, we raise further challenges and possible future research directions for Janus 2D materials as water-splitting photocatalysts.

Abstract: Recently, two-dimensional (2D) transition-metal nitrides have triggered an enormous interest for their tunable mechanical, optoelectronic, and magnetic properties, significantly enriching the family of 2D materials. Here, by using a broad range of first-principles calculations, we report a systematic study of 2D rectangular materials of titanium mononitride (TiN), exhibiting high energetic and thermal stability due to in-plane d-p orbital hybridization and synergetic out-of-plane electronic delocalization. The rectangular TiN monolayer also possesses enhanced auxeticity and ferroelasticity with an alternating order of Possion's Ratios, stemming from the competitive interactions of intra- and inter- Ti-N chains. Such TiN nanosystem is a n-type metallic conductor with specific tunable pseudogaps. Halogenation of TiN monolayer downshifts the Fermi level, achieving the optical energy gap up to 1.85 eV for TiNCl(Br) sheet. Overall, observed electronic features suggest that the two materials are potential photocatalysts for water splitting application. These results extend emerging phenomena in a rich family 2D transition-metal-based materials and hint for a new platform for the next-generation functional nanomaterials.

Abstract: Few-layer black phosphorus (BP) which exhibits excellent optical and electronic properties, has great potential applications in nanodevices. However, BP inevitably suffers from the rapid degradation in ambient air because of the high reactivity of P atoms with oxygen and water, which greatly hinders its wide applications. Herein, we demonstrate the electrostatic functionalization as an effective way to simultaneously enhance the stability and dispersity of aqueous phase exfoliated few-layer BP. The poly dimethyldiallyl ammonium chloride (PDDA) is selected to spontaneously and uniformly adsorb on the surface of few-layer BP via electrostatic interaction. The positive charge-center of the N atom of PDDA, which passivates the lone-pair electrons of P, plays a critical role in stabilizing the BP. Meanwhile, the PDDA could serve as hydrophilic ligands to improve the dispersity of exfoliated BP in water. The thinner PDDA-BP nanosheets can stabilize in both air and water even after 15 days of exposure. Finally, the uniform PDDA-BP-polymer film was used as a saturable absorber to realize passive mode-locking operations in a fiber laser, delivering a train of ultrafast pulses with the duration of 1.2 ps at 1557.8 nm. This work provides a new way to obtain highly stable few-layer BP, which shows great promise in ultrafast optics application.

Abstract: Two‐dimensional materials are excellent candidates for effective gas detection due to the large surface‐volume ratio, however the controllability to adsorb/desorb the gas molecules for recycling use is still a big challenge. In this study, different from previous strategies to modulate gas adsorption behavior via strain and external electric field, a novel approach to achieve gas adsorption control via ferroelectric (FE) switching is proposed. From first principle simulations, it is found that gas molecule adsorptions on Fe and Mn doped defective graphene can be well controlled when it is placed on the surface of FE In 2 Se 3 . The adsorption energies and charge transfer can be significantly modulated when the polarization is reversed, due to the polarization dependent electron redistribution and band state shifts near the Fermi level. The hypothesis of the FE controlled gas adsorption is further supported by the adsorption variations under the electric field. These findings provide feasible approaches and design principles for the next generation gas sensors.

Abstract: The successful fabrication of Janus transition metal dichalcogenide (TMD) monolayer has sparked extensive research interests in various fields, such as nanoelectronics, optoelectronics, valleytronics, and catalysis. Janus TMDs can not only inherit the advantages of conventional TMDs but also produce novel properties which are different from their counterparts. The breaking of vertical mirror symmetry can induce a variety of novel properties, such as Rashba spin splitting, vertical piezoelectricity, and long exciton lifetime. Moreover, the intrinsic electric field that originates from the vertical asymmetry can serve as a superior platform for tuning the interlayer coupling when forming van der Waals structures. In this mini review, the recent key research progresses of 2D Janus TMDs, including the fundamental properties and potential applications, are briefly summarized, and the existing challenges are also presented.

Abstract: Band alignment engineering is crucial and feasible to enrich the functionalities of van der Waals heterojunctions (vdWHs) for rectifying functions in next-generation information storage technologies. However, band alignment tunability is volatile as it needs a sustained external field to maintain the Femi level of single components, which hinders the implementation of nonvolatile functions. Here, the ferroelectric semiconducting nature of alpha-In2Se3 is utilized to design vdWHs based on two-dimensional transition metal dichalcogenides (TMDs)/alpha-In2Se3, where TMDs are used as the channel, and the ferroelectric semiconductor alpha-In2Se3 is assembled as an asymmetric gate. A density functional theory validates that the band offset in a homogeneous TMDs channel is tuned by coupling the effect of the semiconducting nature and asymmetric ferroelectric gate of alpha-In2Se3, which induces simultaneous rectifying and memory functions. This includes a programmable rectifying ratio of up to 104, ultra-large memory window (110 V), programming/erasing of 104, and good endurance. The tuned band offset from the asymmetric ferroelectric semiconductor gate is conceptualized as a guideline to realize a simultaneous rectifying and memory device with high programmability.
