Antimonene: a tuneable post-graphene material for advanced applications in optoelectronics, catalysis, energy and biomedicine

Abstract

Antimonene is considered one of the most promising 2D materials for a large number of applications, ranging from optoelectronics or energy storage to biomedicine. This review discusses recent advances in its synthesis methods, characterization, properties, and applications.

Strain-engineered thermophysical properties ranging from band-insulating to topological insulating phases in β-antimonene

“…3 ). 52 Its optimized lattice parameter 'a' was 4.12 Å, and the Sb-Sb bond length was 2.89 Å. Here, the two vertically displaced sublattices showed the buckling of h (1.64 Å), which agrees with the literature.…”

Prediction of structurally stable two-dimensional AuClO2 with high thermoelectric performance

“…1 As methods in both theory and experiment have advanced, plentiful 2D materials have come into sight, 2 including black phosphorus (BP), 3 transition metal dichalcogenides (TMDs), 4,5 group IVA-VIA compounds, 6 MXenes, 7 graphdiyne, 8 etc. These 2D materials feature unique electronic and mechanical properties thanks to their layered structural characteristics, making their broad application at the foreground in photoelectrochemical devices, [9][10][11] perovskite solar cells, 12 biomedicine, 13 catalysis and energy storage, 14 and nonlinear optics. [15][16][17] Some of these 2D materials, such as layered Bi 2 Te 3 , SnSe, and PbTe, also possess high thermoelectric (TE) performances and have been applied in elds such as power generation, 6,[18][19][20][21][22][23][24][25][26][27] thermal insulation and low power thermoelectric refrigeration, 28,29 owing to their quantum connement effects.…”

Hexagonal Hybrid Bismuthene by Molecular Interface Engineering

“…The field of two-dimensional (2D) materials has blossomed in the past decades due to the extraordinary properties that these materials show upon reduction of their thickness . After sophisticated studies of graphene, the focus of research started to pivot toward heavier layered materials with inherent promising electronic properties, such as MXenes, and transition metal dichalcogenides (TMDCs). , At the frontier of this trend, the group of 2D pnictogens (group 15 of the periodic table) stands out as one of the most appealing, with phosphorene being the first obtained pnictogen that allowed to build field-effect transistors (FETs) with high on/off ratios and excellent mobilities. − Furthermore, one exciting property for the heavy pnictogens, and especially antimony and bismuth, is a strong spin–orbit coupling (SOC) that is crucial for achieving topological surface states and spin orbit torque (SOT) effects, thus opening the door for exotic quantum phenomena and unprecedented opportunities for 2D spintronics and magnonics. − Also, the catalytic activity of this cost efficient material as well as the extremely low toxicity may lead to a wide variety of applications in the foreseeable future. − …”
