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…
Tunable terahertz plasmons in graphite thin films
Qiaoxia Xing, Chaoyu Song, Chong Wang +10
Tunable terahertz plasmons are essential for reconfigurable photonics, which have been demonstrated in graphene through gating, though with relatively weak responses. Here, we demo…
Plasmons in the van der Waals charge-density-wave material 2H-TaSe2
Chaoyu Song, Xiang Yuan, Ce Huang +11
Plasmons in two-dimensional (2D) materials beyond graphene have recently gained much attention. However, the experimental investigation is limited due to the lack of suitable mater…
Tunable plasmons in large area WTe2 thin films
Chong Wang, Yangye Sun, Shenyang Huang +8
The observation of the electrically tunable and highly confined plasmons in graphene has stimulated the exploration of interesting properties of plasmons in other two dimensional m…
From Anomalous to Normal: Temperature Dependence of the Band Gap in Two-Dimensional Black Phosphorus
Shenyang Huang, Fanjie Wang, Guowei Zhang +11
The temperature dependence of the band gap is crucial to a semiconductor. Bulk black phosphorus (BP) is known to exhibit an anomalous behavior. Through optical spectroscopy, here w…
Tunable Graphene Split-Ring Resonators
Qiaoxia Xing, Chong Wang, Shenyang Huang +7
A split-ring resonator is a prototype of meta-atom in metamaterials. Though noble metal-based split-ring resonators have been extensively studied, up to date, there is no experimen…
Van der Waals thin films of WTe2 for natural hyperbolic plasmonic surfaces
Chong Wang, Shenyang Huang, Qiaoxia Xing +4
A hyperbolic plasmonic surface supports highly directional propagating polaritons with extremely large density of states. Such plasmon polaritons have been realized in artificially…
The Optical Properties and Plasmonics of Anisotropic 2-Dimensional Materials
Chong Wang, Guowei Zhang, Shenyang Huang +2
In the fast growing two-dimensional (2D) materials family, anisotropic 2D materials, with their intrinsic in-plane anisotropy, exhibit a great potential in optoelectronics. One suc…
