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 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…
