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…
Graphene plasmonics: Physics and potential applications
Shenyang Huang, Chaoyu Song, Guowei Zhang +1
Plasmon in graphene possesses many unique properties. It originates from the collective motion of massless Dirac fermions and the carrier density dependence is distinctively differ…
Infrared fingerprints of few-layer black phosphorus
Guowei Zhang, Shenyang Huang, Andrey Chaves +4
Black phosphorus is an infrared layered material. Its bandgap complements other widely studied two-dimensional materials: zero-gap graphene and visible/near-infrared gap transition…
