متن کاملTemperature-resonant cyclotron spectra in confined geometries.
We consider a two-dimensional gas of colliding charged particles confined to finite size containers of various geometries and subjected to a uniform orthogonal magnetic field. The gas spectral densities are characterized by a broad peak at the cyclotron frequency. Unlike for infinitely extended gases, where the amplitude of the cyclotron peak grows linearly with temperature, here confinement ca...
متن کاملPlasmon bands in multilayer graphene
High-energy collective electronic excitations (plasmons) in freestanding multilayer graphene are studied by momentum-resolved electron energy-loss spectroscopy (EELS). For normal incidence, only the high-energy plasmon band is excited and we measure a blueshift of the π -plasmon dispersion with increasing thickness. The observed transition between two-dimensional and three-dimensional behavior ...
متن کاملPlasmon resonant coupling in metallic nanowires.
We investigate the plasmon resonances of interacting silver nanowires with a 50 nm diameter. Both non-touching and intersecting configurations are investigated. While individual cylinders exhibit a single plasmon resonance, we observe much more complex spectra of resonances for interacting structures. The number and magnitude of the different resonances depend on the illumination direction and ...
متن کاملOptical monitoring of faradaic reaction using single plasmon-resonant nanorods functionalized with graphene.
Real-time optical monitoring of the electron-transfer process was achieved and modulated on individual gold nanoparticles functionalized with graphene. We found that charge accumulation on single gold nanorods (GNRs) depends on the rate of Faradaic reaction, which is synchronized with double-layer charging.
