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…
Edge and surface plasmons in graphene nanoribbons
Z. Fei, M. D. Goldflam, J. -S. Wu +9
We report on nano-infrared (IR) imaging studies of confined plasmon modes inside patterned graphene nanoribbons (GNRs) fabricated with high-quality chemical-vapor-deposited (CVD) g…
Graphene-Based Platform for Infrared Near-Field Nanospectroscopy of Water and Biological Materials in an Aqueous Environment
Omar Khatib, Joshua D. Wood, Alexander S. McLeod +12
Scattering scanning near-field optical microscopy (s-SNOM) has emerged as a powerful nanoscale spectroscopic tool capable of characterizing individual biomacromolecules and molecul…
Subdiffractional focusing and guiding of polaritonic rays in a natural hyperbolic material
S. Dai, Q. Ma, T. Andersen +11
Uniaxial materials whose axial and tangential permittivities have opposite signs are referred to as indefinite or hyperbolic media. In such materials light propagation is unusual,…
Graphene on hexagonal boron nitride as a tunable hyperbolic metamaterial
S. Dai, Q. Ma, M. K. Liu +13
Hexagonal boron nitride (h-BN) is a natural hyperbolic material, for which the dielectric constants are the same in the basal plane (epsilon^t = epsilon^x = epsilon^y) but have opp…
Ultrafast and Nanoscale Plasmonic Phenomena in Exfoliated Graphene Revealed by Infrared Pump-Probe Nanoscopy
Martin Wagner, Zhe Fei, Alexander S. McLeod +14
Pump-probe spectroscopy is central for exploring ultrafast dynamics of fundamental excitations, collective modes and energy transfer processes. Typically carried out using conventi…
