Recent progress on antimonene: from theoretical calculation to epitaxial growth

Abstract

Monolayer antimony (antimonene) is an emerging 2D material that has recently attracted considerable attention due to its intriguing structure and fascinating electronic properties as theoretically predicted. In order to extensively explore this material in both fundamental research and potential applications, it is important to first prepare high-quality monolayer antimony. In this review, we focus on the theoretical calculations and experimental achievements for both α- and β- phases of antimonene, particularly through the use of molecular beam epitaxy. Moreover, we also provide insight for further exploring the appealing properties of antimonene and other materials with analogous structure.

The marriage of Xenes and hydrogels: Fundamentals, applications, and outlook

“…Xenes exhibit variable stability. Borophene, 30 gallenene, 83 and antimonene 114 , 115 are relatively stable under atmospheric conditions. However, the active surface can damage the stability of Xenes by aggregation or degradation in the environment.…”

Moiré superlattices of antimonene on a Bi(111) substrate with van Hove singularity and Rashba-type spin polarization

“…The most stable form of bulk crystals is the A7 rhombohedral crystal structure, which consists of covalently bonded buckled honeycomb 2D layers (conventionally called "bilayers") stacked by weak interlayer bonding [20][21][22] . This feature makes Bi and Sb atomic layers promising 2D materials beyond graphene [23][24][25] . They were theoretically predicted to become 2D topological insulators (quantum spin Hall insulators), and their topological edge states were found experimentally [26][27][28][29][30][31][32] .…”

“…Here, we show by scanning tunneling microscopy (STM) that single-and double-bilayer (BL) Sb honeycomb lattices, referred to as antimonene 23,25,[34][35][36][37][38] , form moiré superlattices on a Bi(111) substrate due to lattice mismatch. They exhibit clear spectral peaks located near the Fermi level, which show distinctive behaviors regarding the moiré periodicity.…”

A Theoretical Study of Armchair Antimonene Nanoribbons in the Presence of Uniaxial Strain Based on First-Principles Calculations

“…Therefore, without changing the material and without complex doping, antimonene nanoribbons can be applied to form heterostructures, which are widely utilized in electronic and optoelectronic applications . Moreover, the electronic properties of nanoribbons can be adjusted by a variety of methods, one of which is applying strain to the structure. ,− …”
