Engineering Plasmons in Oxide/Graphene Heterostructures via Interfacial Charge Transfer
Yuanchen Chi, Dongxu Di, Michael Fralaide +2
Interfacial charge transfer provides an effective route for tailoring the optical and electronic properties of two-dimensional materials. Here, we investigate infrared surface plas…
Imaging exciton-polariton transport in MoSe2 waveguides
Fengrui Hu, Yilong Luan, M. E. Scott +4
The exciton polariton (EP), a half-light and half-matter quasiparticle, is potentially an important element for future photonic and quantum technologies. It provides both strong li…
Real-space imaging of the tailored plasmons in twisted bilayer graphene
Fengrui Hu, Suprem R Das, Yilong Luan +3
We report a systematic plasmonic study of twisted bilayer graphene (TBLG) - two graphene layers stacked with a twist angle. Through real-space nanoimaging of TBLG single crystals w…
Tailored plasmons in pentacene/graphene heterostructures with interlayer electron transfer
Fengrui Hu, Minsung Kim, Y. Zhang +6
Van der Waals (vdW) heterostructures, which are produced by the precise assemblies of varieties of two-dimensional (2D) materials, have demonstrated many novel properties and funct…
Tip-and plasmon-enhanced infrared nanoscopy for ultrasensitive molecular characterizations
Yilong Luan, Liam McDermott, Fengrui Hu +1
We propose a novel method for ultra-sensitive infrared (IR) vibrational spectroscopy of molecules with nanoscale footprints by combining the tip enhancement of the scattering-type…
Tunable plasmonic reflection by bound 1D electron states in a 2D Dirac metal
Bor-Yuan Jiang, Guangxin Ni, Cheng Pan +6
We show that surface plasmons of a two-dimensional Dirac metal such as graphene can be reflected by line-like perturbations hosting one-dimensional electron states. The reflection…
