Two-dimensional structures of elemental analogues of graphene have received much attention in recent years due to their outstanding properties. Black arsenic is a metastable form of arsenic with an orthorhombic structure similar to black phosphorus. Compared to thermodynamically stable rhombohedral grey arsenic, individual layers are held only by weak van der Waals interactions. Currently black arsenic is available only as an extremely rare naturally occurring mineral arsenolamprite. Herein we… 
Growth of black arsenic phosphorus thin films and its application for field-effect transistors
Black arsenic phosphorus single crystals were grown using a short-way transport technique resulting in crystals up to 12 × 110 μm and ranging from 200 nm to 2 μm thick. The reaction conditions
Black Arsenic as an Optimum Gas Sensor: vdW Corrected Density Functional Theory Calculations
Recent experiments demonstrate the synthesis of 2D black arsenic exhibits excellent electronic and transport properties for nanoscale device applications. Herein, we study by first principle
Stable puckered C2N2 nanosheet with giant anisotropic hole carrier mobility: insights from first-principles
Very recently, a black-phosphorus-like nitrogen (bp-N) bulk has been synthesized in high-pressure experiments [D. Laniel, et al., Phys. Rev. Let., 2020, 124, 216001 and C. Ji, et al., Sci. Adv.,


Synthesis and identification of metastable compounds: black arsenic--science or fiction?
The results show that orthorhombic black arsenic (o-As) is metastable in pure form and has only been previously obtained by stabilizing impurities.
Interlayer Bond Formation in Black Phosphorus at High Pressure
A deep insight is offered on the mechanism of interlayer bond formation during the transformation from the layered A7 to the non‐layered simple‐cubic phase of phosphorus, opening new perspectives for the design, synthesis and stabilization of phosphorene‐based systems.
Black Arsenic: A Layered Semiconductor with Extreme In‐Plane Anisotropy
Systematic characterization of the structural, electronic, thermal, and electrical properties of b-As single crystals is performed, with particular focus on its anisotropies along two in-plane principle axes, armchair (AC) and zigzag (ZZ).
Black Arsenic–Phosphorus: Layered Anisotropic Infrared Semiconductors with Highly Tunable Compositions and Properties
Transport and infrared absorption studies demonstrate the semiconducting nature of b-AsP with tunable bandgaps, which fall into the long-wavelength infrared regime and cannot be readily reached by other layered materials.
On the Allotropy of Arsenic
The system AsHg was investigated using low temperature X-ray diffraction (200 and 120 K). The samples ranging in composition from 1 to 60 at.-% Hg were alternatively slowly cooled and /or quenched
Arsenene: Two-dimensional buckled and puckered honeycomb arsenic systems
Recently, phosphorene, a monolayer honeycomb structure of black phosphorus, was experimentally manufactured and has attracted rapidly growing interest. Motivated by phosphorene, here we investigate
Atomically Thin 2D‐Arsenene by Liquid‐Phased Exfoliation: Toward Selective Vapor Sensing
Phosphorene and antimonene, single‐ or few‐layered (FL) semiconductor materials, have recently attracted enormous attention due to their unique properties, provided by their extreme thinness. Here, a
CVD - technology of transition metal oxides and their impact on solar energy utilization
The paper presents results concerning CVD thin films of transition metals (W and Mo) and their composite structures WO 2 :W and MoO 2 :Mo, as well as WO 3 films. The composite structure materials
The structures of orthorhombic and vitreous arsenic
Abstract The structure of the orthorhombic crystal modification of arsenic has been determined from an analysis of X-ray powder diffraction data. The structure is confirmed as being similar to that
