“…Stone-Wales defect and divacancy in silicene can induce small band gaps, while monovacancy defects may transform semimetallic silicene into metal. [198] Moreover, monovacancy silicene has much higher mobility than divacancy silicone. [167] Researches show that the monovacancy BP is a semiconductor with direct band gap, while the divacancy induces the transition from direct to indirect band gap.…”

As a new type of two‐dimensional (2D) materials, monoelemental 2D materials have the atomic structure similar to graphene, and their excellent optical and electronic properties have potential applications in many fields. To date, many studies based on monoelemental 2D materials have been reported, and excellent performance has been demonstrated in various fields. The monoelemental 2D materials that have been reported so far are mainly distributed in the group IIIA, IVA, VA, and VIA. Because of their structural similarities to graphene, they are commonly referred to as "Xenes." Here, we have comprehensively reviewed the research progress of monoelemental 2D materials. In this review, we explore the structure, properties, and practical applications of these monoelemental 2D materials. First, the classification, structural features, optical properties, electronic characteristics, and regulating mechanism of these monoelemental 2D materials are introduced. Then, the practical application and research progress of monoelemental 2D materials in various fields are reviewed comprehensively, especially including photoelectric catalysis, solar cells, and other energy fields. This review will give readers a more all‐sided understanding of monoelemental 2D materials and have some guiding significance for their further development.

“…74 The diffusion barrier for Li and Na migrations is calculated to be 0.25 eV. 75,76 Transition metal atoms are predicted to introduce spinpolarization gaps in silicene due to the localized d electrons, which enables applications in spintronics. The binding energies of the elements Sc to Zn are larger than the corresponding cohesive energies, reflecting stability.…”

Silicene is a two-dimensional allotrope of silicon with a puckered hexagonal structure closely related to the structure of graphene and that has been predicted to be stable. To date, it has been successfully grown in solution (functionalized) and on substrates. The goal of this review is to provide a summary of recent theoretical advances in the properties of both free-standing silicene as well as in interaction with molecules and substrates, and of proposed device applications.

“…29,30 The eldeffect transistors based on the silicene has been fabricated by Li's group. 31 The adsorption of some adatoms on silicene has been studied [32][33][34][35][36] and the buckled silicene shows strong adsorption of the adatoms. The electronic properties of silicene can be modied by the adsorption of adatoms.…”
