Electrically-Tunable High Curie Temperature Two-Dimensional Ferromagnetism in Van der Waals Layered Crystals
Hua Wang, Jingshan Qi, Xiaofeng Qian
Identifying intrinsic low-dimensional ferromagnets with high transition temperature and electrically tunable magnetism is crucial for the development of miniaturized spintronics an…
Two-Dimensional Multiferroic Semiconductors with Coexisting Ferroelectricity and Ferromagnetism
Jingshan Qi, Hua Wang, Xiaofang Chen +1
Low-dimensional multiferroicity, though highly scarce in nature, has attracted great attention due to both fundamental and technological interests. Using first-principles density f…
On the quantum spin Hall gap of monolayer 1T'-WTe2
Feipeng Zheng, Chaoyi Cai, Shaofeng Ge +12
Quantum spin Hall (QSH) materials are two-dimensional systems exhibiting insulating bulk and helical edge states simultaneously. A QSH insulator processes topologically non-trivial…
The electronic origin of shear-induced direct to indirect gap transition and anisotropy diminution in phosphorene
Baisheng Sa, Yan-Ling Li, Zhimei Sun +3
Artificial monolayer black phosphorus, the so-called phosphorene has attracted global interest with its distinguished anisotropic optoelectronic and electronic properties. Here, we…
