Gate-tunable negative refraction of mid-infrared polaritons
Hai Hu, Na Chen, Hanchao Teng +11
Negative refraction provides an attractive platform to manipulate mid-infrared and terahertz radiation for molecular sensing and thermal radiation applications. However, its implem…
Doping-driven topological polaritons in graphene/α-MoO3 heterostructures
Hai Hu, Na Chen, Hanchao Teng +15
Controlling the charge carrier density provides an efficient way to trigger phase transitions and modulate the optoelectronic properties in natural materials. This approach could b…
Investigation of plasmonic evolution of atomically size-selected Au clusters by electron energy loss spectrum--from solid state to molecular scale
Siqi Lu, Lin Xie, Kang Lai +13
Versatile quantum modes emerge for plasmon describing the collective oscillations of free electrons in metallic nanoparticles when the particle sizes are greatly reduced. Rather th…
Ultralong Lifetime Plasmons on Picosecond Time Scale Enabled by Hybrid Plasmon-Phonon Polaritons
Xiaoxia Yang, Feng Zhai, Hai Hu +4
Graphene plasmonics is of great interest for compact optical devices working in broad frequency domains with ultrahigh speed and very low energy consumption. However, graphene plas…
