“…155 Promising indications of broadband use of antimonene as a photodetector or optical modulator have been shown recently. 181,182 It was commented earlier by Xu et al 183 that significant absorption from the visible region to the ultraviolet region can be observed in aw-Sb, while Ares et al 62 reviewed its properties and commented on Sb to have a suitable tunable bandgap for use in optoelectronics. In another study by Singh et al, 171 it was found via the dielectric function and electron loss spectra that plasmon energies around 9 eV and parts of the electromagnetic spectrum make antimonene behave like a metal in terms of reflectivity of light.…”

Soon after the synthesis of two-dimensional (2D) ultrathin black phosphorus and fabrication of field effect transistors thereof, theoretical studies have predicted that other group-VA elements (or pnictogens), N, As, Sb, and Bi can also form stable, single-layer (SL) structures. These were nitrogene in a buckled honeycomb structure, arsenene, antimonene, and bismuthene in a buckled honeycomb, as well as washboard and square-octagon structures with unusual mechanical, electronic, and optical properties. Subsequently, theoretical studies are followed by experimental efforts that aim at synthesizing these novel 2D materials. Currently, research on 2D pnictogens has been a rapidly growing field revealing exciting properties, which offers diverse applications in flexible electronics, spintronics, thermoelectrics, and sensors. This review presents an evaluation of the previous experimental and theoretical studies until 2019, in order to provide input for further research attempts in this field. To this end, we first reviewed 2D, SL structures of group-VA elements predicted by theoretical studies with an emphasis placed on their dynamical and thermal stabilities, which are crucial for their use in a device. The mechanical, electronic, magnetic, and optical properties of the stable structures and their nanoribbons are analyzed by examining the effect of external factors, such as strain, electric field, and substrates. The effect of vacancy defects and functionalization by chemical doping through adatom adsorption on the fundamental properties of pnictogens has been a critical subject. Interlayer interactions in bilayer and multilayer structures, their stability, and tuning their physical properties by vertical stacking geometries are also discussed. Finally, our review is concluded by highlighting new research directions and future perspectives on the challenges in this emerging field.

“…46 Promising indications of antimonene's broadband use as a photodetector or optical modulator have been shown recently. 47,48 Bismuthene's optical properties have not been vastly investigated yet, with only a few recent examples of electric field applications or its potential as a photonic-based device, 45,[49][50][51] hence the light-matter interaction within 2D bismuthene remains an area of interest. While the dynamical stability, electronic structure and topological features of SL BiSb binary compounds have been studied actively, 34,35,[52][53][54][55][56] very little is known about their optical properties.…”

“…Inspired by a few preliminary studies, the anisotropy effects and the unique properties of pnictogen on the device performances have been extensively investigated in experiment and theory [59, 78, 79]. For instance, anisotropic photocurrent generation in black phosphorus FETs has been investigated through resolved polarization-dependent photocurrent characterization [80].…”

Two-dimensional (2D) layered materials hold great promise for various future electronic and optoelectronic devices that traditional semiconductors cannot afford. 2D pnictogen, group-VA atomic sheet (including phosphorene, arsenene, antimonene, and bismuthene) is believed to be a competitive candidate for next-generation logic devices. This is due to their intriguing physical and chemical properties, such as tunable midrange bandgap and controllable stability. Since the first black phosphorus field-effect transistor (FET) demo in 2014, there has been abundant exciting research advancement on the fundamental properties, preparation methods, and related electronic applications of 2D pnictogen. Herein, we review the recent progress in both material and device aspects of 2D pnictogen FETs. This includes a brief survey on the crystal structure, electronic properties and synthesis, or growth experiments. With more device orientation, this review emphasizes experimental fabrication, performance enhancing approaches, and configuration engineering of 2D pnictogen FETs. At the end, this review outlines current challenges and prospects for 2D pnictogen FETs as a potential platform for novel nanoelectronics.
