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…
Tunneling Plasmonics in Bilayer Graphene
Z. Fei, E. G. Iwinski, G. X. Ni +14
We report experimental signatures of plasmonic effects due to electron tunneling between adjacent graphene layers. At sub-nanometer separation, such layers can form either a strong…
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…
