Surface plasmon polaritons (SPP) are electromagnetic waves bound by the collective oscillations of free carrier plasma to the surface of a conductor surrounded by dielectric. These waves can be localized, concentrated or manipulated simply by processing the conductor surface. The choice of a convenient conductor is quite limited by the availability of natural materials and strong absorption losses associated with free electron plasma. For this reason new alternative plasmonic materials are…

Ultrasmooth Patterned Metals for Plasmonics and Metamaterials
TLDR
This work combined template stripping with precisely patterned silicon substrates to obtain ultrasmooth pure metal films with grooves, bumps, pyramids, ridges, and holes, and measured surface-plasmon–propagation lengths on the resulting surfaces approach theoretical values for perfectly flat films.
Searching for better plasmonic materials
TLDR
A comparative study of various materials including metals, metal alloys and heavily doped semiconductors is presented and an approach for realizing optimal plasmonic material properties for specific frequencies and applications is outlined.

TLDR
The reflectance and the phase change on reflection from semiconductor-metal interfaces (including the case of metallic multilayers) can be accurately described by use of the proposed models for the optical functions of metallic films and the matrix method for multilayer calculations.
