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…
Phase transition in bulk single crystals and thin films of VO2 by nano-infrared spectroscopy and imaging
Mengkun Liu, Aaron J. Sternbach, Martin Wagner +21
We have systematically studied a variety of vanadium dioxide (VO2) crystalline forms, including bulk single crystals and oriented thin films, using infrared (IR) near-field spectro…
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…
