When ellipsometry works best: a case study with transparent conductive oxides

Autor: Christopher J. Mellor, Demosthenes C. Koutsogeorgis, S. Camelio, Wayne Cranton, James Arthur Hillier, Nikolaos Kalfagiannis, Alexei Nabok

As the library of potential materials with plasmonic behavior in the infrared (IR) grows, we must carefully assess their suitability for nanophotonic applications. This assessment relies on knowledge of the materials’ optical constants, best determ

Structure and far‐field optical properties of self‐organized bimetallic Au x ‐Ag 1– x nanoparticles embedded in alumina thin films

Autor: Frédéric Pailloux, David Babonneau, Sophie Rousselet, S. Yazidi, Alexandre Fafin, S. Camelio

Publikováno v: physica status solidi c. 12:1344-1348

Self-organized Aux-Ag1–x nanoparticles were produced by grazing-angle deposition using alternating sources on alumina nanoripple patterns. Structural and far-field optical studies showed that periodic chains of Aux-Ag1–x alloy nanoparticles with
