In a recent study, interaction of various gases with stanene was investigated by Garg et al where the author found that stanene gas systems show Rashba type spin‐splitting, which is very promising for spintronics applications …”

“…Luo et al studied doping of B and N in phagraphene NRs and predicted that while B‐doping removed/changed the bandgap depending on doping position, N or BN doping increased the bandgap . Garg et al patterned stanene with BN doping and predicted a bandgap opening of ≈0.22 eV, and a semiconducting behavior sustained under applied strain …”

“…Other elemental 2D materials are predicted to exhibit advantageous sensing properties, but have yet to be fabricated and experimentally tested. Garg et al modeled the potential effectiveness of B, N, and BN‐doped stanene as a sensors for several gases, where doping provided both higher sensitivity and selectivity . Arsenene has been predicted to be a promising candidate for sensing NO, NO 2, and SO 2 , as the molecules interact strongly with the elemental 2D material and can create a measureable and detectable change in magnetic moment .…”

As elemental main group materials (i.e., silicon and germanium) have dominated the field of modern electronics, their monolayer 2D analogues have shown great promise for next‐generation electronic materials as well as potential game‐changing properties for optoelectronics, energy, and beyond. These atomically thin materials composed of single atomic variants of group III through group VI elements on the periodic table have already demonstrated exciting properties such as near‐room‐temperature topological insulation in bismuthene, extremely high electron mobilities in phosphorene and silicone, and substantial Li‐ion storage capability in borophene. Isolation of these materials within the postgraphene era began with silicene in 2010 and quickly progressed to the experimental identification or theoretical prediction of 15 of the 18 main group elements existing as solids at standard pressure and temperatures. This review first focuses on the significance of defects/functionalization, discussion of different allotropes, and overarching structure–property relationships of 2D main group elemental materials. Then, a complete review of emerging applications in electronics, sensing, spintronics, plasmonics, photodetectors, ultrafast lasers, batteries, supercapacitors, and thermoelectrics is presented by application type, including detailed descriptions of how the material properties may be tailored toward each specific application.

The 2D graphene (G) nanosheets (NSs) discovery is amound the foremost revolutionary incidents in materials science history. This discovery has stimulated huge attention in the study of other novel 2D materials (2DMs). This trend might be called modern day "alchemy," where the basic aim is to convert most of periodic table elements into G like 2D structures. Monoelemental, atomically thin 2DMs, called "Xenes" ("X" = group (III-VI)A elements, "ene" suffix that indicates one atom thick 2D layer of atoms) which are a newly invented family among nanomaterials. The number of predicted and experimentally synthesized 2D Xene materials of group IVA, i.e., G's siblings, has gained attention in nanosize devices. Such materials involve buckle structures that have recently been experimentally fabricated. The 2D Xene materials analog to G offer exciting potential for novel sensing applications. The group IVA Xenes, in cooperation with their ligandfunctionalized derivatives, arrange in a honeycomb lattice analogous to G but through a changeable degree of buckling. Their electronic structure ranges from trivial insulators passing via semiconductors with tunable gaps, to semimetallic, depending on substrate, chemical functionalization, and strain. In this review, different potential synthesis methods for group IVA 2D Xenes are briefly presented. A brief overview of their properties obtained theoretically and experimentally is presented, and finally their potential sensing applications are discussed.

for example, incompatibility with the semiconductor industry, [13] toxicity, [14] and susceptibility to oxidative environments. [7] Accordingly, researchers are on the lookout for other existing or synthetic 2D analogues.There have been numerous reports describing a wide variety of layered ultrathin 2D nanomaterials beyond graphene, with fascinating and technologydriven properties. These single-layer atomic crystals are classified in terms of their constituent elemental bonding states and structures. Most of them are transition metals bonded with chalcogenide groups (e.g., MoS 2 , MoSe 2 , WS 2 , TiS 2 ), [13,15] metal carbides and nitrides (MXenes), [16] metalorganic frameworks (MOFs), [17] covalent organic frameworks (COFs), [18] hexagonal boron nitrides, [19] and monoelemental 2D analogues (e.g., silicene, germanene, and phosphorene). [20] The emergence of new fascinating physical and chemical properties is encouraging the discovery of new classes of 2D nanomaterials, prepared either from 3D van der Waals bulk phases (through top-down techniques) or through self-assembly of elemental constituents from wet-chemical or vapor phase (bottom-up approaches). The former types of synthetic strategies are mostly exfoliation processes from 3D layered structures, including physical exfoliation (by forced delamination of layers), [21] liquid phase exfoliation (by the chemistry of matching with solute-solvent interface energy), [22] and ion intercalation and exfoliation (by electrochemical reactions). [23,24] These processes for preparing 2D nanosheets are widely followed because they are sufficiently simple and robust for scalable production; nevertheless, they can be challenging to use when synthesizing nanosheets with uniform thicknesses and lateral dimensions. The scalability of these processes for manufacturing nanosheets has, however, been exploited widely, for example, in energy storage devices, [25] sensors, [26] electronics and photonic devices, [27] as well as in biomedicine. [27] The bottom-up approaches involve growth and self-assembly from the atomic scale, mostly involving chemical vapor deposition, [28] pulsed laser deposition, [28] and epitaxial growth. [29] Although these processes for fabricating 2D nanosheets provide good control over the homogeneity of the structures, they occur with complex growth mechanisms and are not scalable. Interestingly, quantum confinement effects are prominent in fabricated atomic-layer structures, and suggest a new dimension for future nanoelectronics and many other advanced applications. [30][31][32][33] Advancements in 2D nanomaterials have been impacting a wide range of technology-driven applications. Here, the authors highlight stanene, a material that comprises a monolayer of elemental tin atoms, as a new addition to the monoelemental 2D family. Recent successes in the experimental realization of stanene in supported heterostructures and in free-standing form have expanded interest in exploring and unlocking its potential applications, as predicted from advanced theoreti...
