2019年3月11日 · We report structural properties, physical properties, and the electronic structure of van der Waals (vdW) crystal VI 3. Detailed analysis reveals that VI 3 exhibits a structural transition from monoclinic C 2/ m to rhombohedral R 3̅ at Ts ≈ 79 K, similar to CrX 3 (X = Cl, Br, I).

Here we propose the van der Waals (vdW) material VI3 to be a 2D Ising ferromagnet (FM), using density functional calculations, crystal field level diagrams, superexchange model analyses, and Monte Carlo simulations.

2020年9月15日 · One of the family numbers, i.e., layered van-der-Waals VI 3 crystal, has been widely studied, yet little has been revealed for its monolayer counterpart. Herein, electronic and magnetic behaviour has been studied, based on density functional theory, including both electron correlation (U) and spin–orbit coupling (SOC).

2021年4月1日 · Here, we investigate the VI3 crystal structures at low temperature using both synchrotron x-ray and neutron powder diffraction and provide structural models for the two structural transitions ...

We report the air-sensitivity, atomic structure, and magnetic anisotropy of VI3 single crystals. We find that VI3 nanocrystals exhibit a large MR/MS ratio of around 0.75 and a uniaxial anisotropic constant of an order of 105 erg cc−1 below the Curie temperature.

2019年3月6日 · VI3, a new layered ferromagnetic semiconductor, is discovered. VI6 octahedra form edge-sharing honeycomb layers, which are separated by an iodine–iodine van der Waals gap. VI3 becomes ferromagnetic b...

2021年10月10日 · 近日，吉林大学李贤斌教授小组与清华大学孙洪波教授、伦斯勒理工学院张绳百教授联合在 Applied Physics Reviews 发表研究论文“Mexican-hat potential energy surface in two-dimensional III2-VI3 materials and the importance of entropy barrier in ultrafast reversible ferroelectric phase change”，该论文通过第一性原理计算报道了二维In2Se3材料的一种赝中心对称顺电相，该相中间层Se原子呈现出墨西哥帽势能面特点，这类Se虽在时间平均上处于中心对 …

2021年4月1日 · The discovery of ferromagnetism is reported in a layered van der Waals semiconductor, VI3, which is based on honeycomb vanadium layers separated by an iodine-iodine van derWaals gap, and experimental evidence suggests that it may undergo a subtle structural phase transition at 78 K.
