Unconventional ferroelectric domain switching dynamics in CuInP2S6 from first principles
Ri He, Hua Wang, Fucai Liu +3
The switching dynamics of ferroelectric materials is a crucial intrinsic property which directly affects the operation and performance of ferroelectric devices. In conventional fer…
Complex Dirac-like Electronic Structure in Atomic Site Ordered Rh3In3.4Ge3.6
Aikaterini Flessa Savvidou, Judith K. Clark, Hua Wang +6
We report the synthesis via an indium flux method of a novel single-crystalline compound Rh3In3.4Ge3.6 that belongs to the cubic Ir3Ge7 structure type. In Rh3In3.4Ge3.6, the In and…
Giant nonlinear photocurrent in -symmetric magnetic topological quantum materials
Hua Wang, Xiaofeng Qian
Nonlinear photocurrent in time-reversal invariant noncentrosymmetric systems have attracted substantial interest. Here we propose two new types of second-order nonlinear direct pho…
Berry curvature memory through electrically driven stacking transitions
Jun Xiao, Ying Wang, Hua Wang +9
In two-dimensional layered quantum materials, the stacking order of the layers determines both the crystalline symmetry and electronic properties such as the Berry curvature, topol…
Ferroelectric nonlinear anomalous Hall effect in few-layer WTe
Hua Wang, Xiaofeng Qian
Under broken time reversal symmetry such as in the presence of external magnetic field or internal magnetization, a transverse voltage can be established in materials perpendicular…
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…
