Negative refraction in hyperbolic hetero-bicrystals
A. J. Sternbach, S. L. Moore, A. Rikhter +12
We visualized negative refraction of phonon polaritons, which occurs at the interface between two natural crystals. The polaritons - hybrids of infrared photons and lattice vibrati…
Infrared Plasmons Propagate through a Hyperbolic Nodal Metal
Yinming Shao, Aaron J. Sternbach, Brian S. Y. Kim +16
Metals are canonical plasmonic media at infrared and optical wavelengths, allowing one to guide and manipulate light at the nano-scale. A special form of optical waveguiding is aff…
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…
Artifact Free Transient Near-Field Nanoscopy
Aaron Sternbach, James Hinton, Tetiana Slusar +11
We report on the first implementation of ultrafast near field nanoscopy carried out with the transient pseudoheterodyne detection method (Tr-pHD). This method is well suited for ef…
