Substrate-sensitive mid-infrared photoresponse in graphene.
We report mid-infrared photocurrent spectra of graphene nanoribbon arrays on SiO2 dielectrics showing dual signatures of the substrate interaction. First, hybrid polaritonic modes of graphene plasmons and dielectric surface polar phonons produce a thermal photocurrent in graphene with spectral features that are tunable by gate voltage, nanoribbon width, and light polarization. Second, phonon po...
متن کاملRealization of mid-infrared graphene hyperbolic metamaterials
While metal is the most common conducting constituent element in the fabrication of metamaterials, graphene provides another useful building block, that is, a truly two-dimensional conducting sheet whose conductivity can be controlled by doping. Here we report the experimental realization of a multilayer structure of alternating graphene and Al2O3 layers, a structure similar to the metal-dielec...
متن کاملNear-infrared electro-optic modulator based on silicon- graphene hybrid structure
Graphene has strong electro-optic effect which can be used to enhance the modulation efficiency of nanoscale photonic circuit. This paper describes recent developments for nearinfrared electro-optic modulator based on silicon-graphene hybrid structure.

متن کاملNear-infrared electro-optic modulator based on plasmonic graphene.
We propose a novel scheme for an electro-optic modulator based on plasmonically enhanced graphene. As opposed to previously reported designs where the switchable absorption of graphene itself was employed for modulation, here a graphene monolayer is used to actively tune the plasmonic resonance condition through the modification of interaction between optical field and an indium tin oxide (ITO)...
متن کاملElectrically driven jets BY SIR
Fine jets of slightly conducting viscous fluids and thicker jets or drops of less viscous ones can be drawn from conducting tubes by electric forces. As the potential of the tube relative to a neighbouring plate rises, viscous fluids become nearly conical and fine jets come from the vertices. The potentials at which these jets or drops first appear was measured and compared with calculations. T...
