Nano-photocurrent mapping of local electronic structure in twisted bilayer graphene
Sai S. Sunku, Alexander S. McLeod, Tobias Stauber +10
We report a combined nano-photocurrent and infrared nanoscopy study of twisted bilayer graphene (TBG) enabling access to the local electronic phenomena at length scales as short as…
Photonic crystals for nano-light in moiré graphene superlattices
S. S. Sunku, G. X. Ni, B. -Y. Jiang +10
Graphene is an atomically thin plasmonic medium that supports highly confined plasmon polaritons, or nano-light, with very low loss. Electronic properties of graphene can be drasti…
Theory of plasmon reflection by a 1D junction
Bor-Yuan Jiang, Eugene J. Mele, Michael M. Fogler
We present a comprehensive study of the reflection of normally incident plasmon waves from a low-conductivity 1D junction in a 2D conductive sheet. Rigorous analytical results are…
Plasmon reflections by topological electronic boundaries in bilayer graphene
Bor-Yuan Jiang, Guang-Xin Ni, Zachariah Addison +7
Domain walls separating regions of AB and BA interlayer stacking in bilayer graphene have attracted attention as novel examples of structural solitons, topological electronic bound…
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…
Generalized spectral method for near-field optical microscopy
B. -Y. Jiang, L. M. Zhang, A. H. Castro Neto +2
Electromagnetic interaction between a sub-wavelength particle (the `probe') and a material surface (the `sample') is studied theoretically. The interaction is shown to be governed…
Infrared nano-spectroscopy and imaging of collective superfluid excitations in conventional and high-temperature superconductors
H. T. Stinson, J. S. Wu, B. Y. Jiang +8
We investigate near-field infrared spectroscopy and superfluid polariton imaging experiments on conventional and unconventional superconductors. Our modeling shows that near-field…
