Geometry Dependent Localization of Surface Plasmons on Random Gold Nanoparticle Assemblies
Mohammed Fayis Kalady, Johannes Schultz, Kristina Weinel +2
Assemblies of plasmonic nanoparticles (NPs) support hybridized modes of localized surface plasmons (LSPs), which delocalize in geometrically well-ordered arrangements. Here, the hy…
Maximal Anderson Localization and Suppression of Surface Plasmons in Two-Dimensional Random Au Networks
Johannes Schultz, Karl Hiekel, Pavel Potapov +4
Two-dimensional random metal networks possess unique electrical and optical properties, such as almost total optical transparency and low sheet resistance, which are closely relate…
Tailoring Plasmonics of Au@Ag Nanoparticles by Silica Encapsulation
Johannes Schultz, Felizitas Kirner, Pavel Potapov +3
Hybrid metallic nanoparticles encapsulated in oxide shells are currently intensely studied for plasmonic applications in sensing, medicine, catalysis, and photovoltaics. Here, we i…
Axion Mie Theory of Electron Energy Loss Spectroscopy in Topological Insulators
Johannes Schultz, Flavio S. Nogueira, Bernd Büchner +2
Electronic topological states of matter exhibit novel types of responses to electromagnetic fields. The response of strong topological insulators, for instance, is characterized by…
Direct Observation of Plasmon Band Formation and Delocalization in Quasi-Infinite Nanoparticle Chains
Martin Mayer, Pavel L. Potapov, Darius Pohl +6
Chains of metallic nanoparticles sustain strongly confined surface plasmons with relatively low dielectric losses. To exploit these properties in applications,such as waveguides, t…
Spectral field mapping in plasmonic nanostructures with nanometer resolution
J. Krehl, G. Guzzinati, J. Schultz +7
Plasmonic nanostructures and devices are rapidly transforming light manipulation technology by allowing to modify and enhance optical fields on sub-wavelength scales. Advances in t…
