2021年5月5日 · Here we report synergetic effects between SOC and the Stark effect in centrosymmetric few-layer black arsenic, which manifest as particle–hole asymmetric Rashba valley formation and exotic...

2018年6月11日 · Here, a rare chemical form of arsenic, called black-arsenic (b-As), is reported as a cousin of black phosphorus, as an extremely anisotropic layered semiconductor.

2020年12月17日 · High-performance photodetection based on black arsenic utilizing the photoconductive effect. Optical Materials Express 2024, 14 (6) , 1446. https://doi.org/10.1364/OME.522882

2022年9月19日 · Black arsenic (BAs) has emerged to be an interesting elemental layered material after graphite and black phosphorus (BP), which can be exfoliated to yield high-quality two-dimensional flakes. Transport measurements have revealed its strong in-plane anisotropy, giant Stark effect, and strong spin-orbital coupling, all resulting from its special ...

Black arsenic is a layered semiconductor with extreme in-plane anisotropy. Similar to its cousin black phosphorus, it exhibits high electronic mobility, thermal conductivity, and anistropic excitons along or across the arsenic chain direction.

Here, a rare chemical form of arsenic, called black-arsenic (b-As), is reported as a cousin of black phosphorus, as an extremely anisotropic layered semiconductor. Systematic characterization of the structural, electronic, thermal, and electrical properties of b-As single crystals is performed, with particular focus on its anisotropies along ...

2018年5月1日 · Herein, we report a rare chemical form of arsenic, called black-arsenic (b-As), as an extremely anisotropic layered semiconductor. We have performed systematic characterization on the structural, electronic, thermal and electrical properties of b-As single crystals, with particular focus on its anisotropies along two in-plane principle axes ...

2020年8月1日 · In contrast to b-P, another group-VA element crystal, arsenic, also has the layered structure. Arsenic usually has three allotropes in nature: gray arsenic, yellow arsenic and black arsenic (b-As).

2025年2月12日 · We report high-pressure Raman spectra and resistance measurements of black arsenic (b-As) up to 58 GPa, along with phonon density of states and enthalpy calculations for four reported arsenic phases up to 50 GPa. It is found that metastable b-As transforms into gray arsenic (g-As) phase at a critical pressure of 1.51 GPa, followed by subsequent transitions to …

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.
