Plasmon Polaritons

We consider dissipative Dyakonov plasmon-polaritons as surface waves propagating along the plane boundary of a hyperbolic metamaterial with an arbitrary orientation of the crystallographic axis. Conditions for the existence of fast, slow, gliding flowing, forward and backward plasmon-polaritons are found. A waveguide in the form of an asymmetric layer of a hyperbolic metamaterial is also considered. An expression for the density of electromagnetic energy in such a metamaterial is given.

Nonlinear Disturbances

A nonlinear equation for electrostatic electron surface waves at the boundary between a cold plasma and a dielectric is derived. Our analysis of this equation shows that the nonlinear disturbances at the plasma–dielectric interface may take the form of periodic travelling waves or standing waves with oscillating amplitudes. While the travelling waves are always periodic in space, the standing waves can be both periodic and localized.

Metal-assisted chemical etching (MACE) is applied for fabrication of silicon nanowires (SiNWs). We have shown the effect of amorphous sheath of SiNWs by treating the nanowires with SF6 and the resulting reduction of absorption bandwidth, i.e. making SiNWs semi-transparent in near-infrared (IR). For the first time, by treating the fabricated SiNWs with copper containing HF∕H2O2∕H2O solution, we have generated crystalline nanowires with broader light absorption spectrum, up to λ = 1 μm. Both the absorption and photo-luminescence (PL) of the SiNWs are observed from visible to IR wavelengths. It is found that the SiNWs have PL at visible and near Infrared wavelengths, which may infer presence of mechanisms such as forbidden gap transitions other can involvement of plasmonic resonances. Non-radiative recombination of excitons is one of the reasons behind absorption of SiNWs. Also, on the dielectric metal interface, the absorption mechanism can be due to plasmonic dissipation or plasmon-assisted generation of excitons in the indirect band-gap material. Comparison between nanowires with and without metallic nanoparticles has revealed the effect of nanoparticles on absorption enhancement. The broader near IR absorption, paves the way for applications like hyperthermia of cancer while the optical transition in near IR also facilitates harvesting electromagnetic energy at a broad spectrum from visible to IR.
