Mechanically Assisted Symmetry Reconstruction for Extraordinary Piezoelectricity
Jinhui Fan, Chonghe Wang, Xiaoyan Lu +16
Active symmetry control - a central challenge in materials science, particularly in ferroelectrics - is achieved via mechanically assisted poling (MAP) guided by thermodynamics and…
Layer-dependent exciton polarizability and the brightening of dark excitons in few-layer black phosphorus
Yuchen Lei, Junwei Ma, Jiaming Luo +11
The evolution of excitons from 2D to 3D is of great importance in photo-physics, yet the layer-dependent exciton polarizability has not been investigated in 2D semiconductors. Here…
Twist-angle and thickness-ratio tuning of plasmon polaritons in twisted bilayer van der Waals films
Chong Wang, Yuangang Xie, Junwei Ma +13
Stacking bilayer structures is an efficient way to tune the topology of polaritons in in-plane anisotropic films, e.g., by leveraging the twist angle (TA). However, the effect of a…
Tunable optical topological transitions of plasmon polaritons in WTe2 van der Waals films
Yuangang Xie, Chong Wang, Fucong Fei +9
Naturally existing in-plane hyperbolic polaritons and the associated optical topological transitions, which avoid the nano-structuring to achieve hyperbolicity, can outperform thei…
Layer-dependent pressure effect on electronic structures of 2D black phosphorus
Shenyang Huang, Yang Lu, Fanjie Wang +11
Through infrared spectroscopy, we systematically study the pressure effect on electronic structures of few-layer black phosphorus (BP) with layer number ranging from 2 to 13. We re…
Prediction of hyperbolic exciton-polaritons in monolayer black phosphorus
Fanjie Wang, Chong Wang, Andrey Chaves +8
Hyperbolic polaritons exhibit large photonic density of states and can be collimated in certain propagation directions. The majority of hyperbolic polaritons are sustained in man-m…
