Bright dipolar excitons in twisted black phosphorus homostructures
Shenyang Huang, Boyang Yu, Yixuan Ma +12
Bright dipolar excitons, which contain electrical dipoles and have high oscillator strength, are an ideal platform for studying correlated quantum phenomena. They usually rely on c…
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…
Anisotropic Infrared Response and Orientation-dependent Strain-tuning of the Electronic Structure in Nb2SiTe4
Fanjie Wang, Yonggang Xu, Lei Mu +6
Two-dimensional materials with tunable in-plane anisotropic infrared response promise versatile applications in polarized photodetectors and field-effect transistors. Black phospho…
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…
