Plasmonics, 11(3), 865-874

Technical applications of plasmonic nanostructures require a careful structural optimization with respect to the desired functionality. The success of such optimizations strongly depends on the applied method. We extend the generalized multiparticle

Surface-plasmon-polariton hybridized cavity modes in submicrometer slits in a thin Au film

Autor: S. Fritz, Kurt Busch, Christian Matyssek, Dagmar Gerthsen, Roman Walther, Hagai Cohen, Tsofar Maniv, Reinhard Schneider, Erich A. Müller

Publikováno v: Physical Review B. 93

The excitation of cavity standing waves in double-slit structures in thin gold films, with slit lengths between 400 and 2560 nm, was probed with a strongly focused electron beam in a transmission electron microscope. The energies and wavelengths of c

Structure-induced resonant tail-state regime absorption in polymer: fullerene bulk-heterojunction solar cells

Autor: Daniel Sommer, Christian Matyssek, Johannes Boneberg, Lukas Schmidt-Mende, Jonas Weickert, Martin Stark, Thomas Kiel, Kurt Busch, Julia F. M. Werra, Thomas Pfadler

Publikováno v: Physical Review B. 93

In this work, we present resonant tail-state regime absorption enhanced organic photovoltaics. We combine periodically structured ${\mathrm{TiO}}_{2}$ bottom electrodes with P3HT-PCBM bulk-heterojunction solar cells in an inverted device configuratio

Ultrafast three-wave-mixing in plasmonic nanostructures

Autor: Kurt Busch, Christian Wolff, Christian Matyssek, Dan-Nha Huynh, Matthias Moeferdt

Publikováno v: Applied Physics B. 122

We present a perturbative approach to the time-domain computation of three-wave-mixing signals from plasmonic nanostructures. Based on a hydrodynamic material model which features nonlinear as well as nonlocal characteristics, we compute the ultrafas

Computing electron energy loss spectra with the Discontinuous Galerkin Time-Domain method

Autor: Wolfram Hergert, Christian Matyssek, Kurt Busch, Jens Niegemann

Publikováno v: Photonics and Nanostructures - Fundamentals and Applications. 9:367-373

In this work, we demonstrate how to extract electron energy loss spectra of metallic nano-particles from time-domain computations. Specifically, we employ the Discontinuous Galerkin Time-Domain (DGTD) method in order to model the excitation of indivi

Real space imaging of nano-tip plasmons using electron energy-loss spectroscopy

Autor: Thomas Kiel, Stefan Linden, Sascha Schäfer, Benjamin Schröder, Kurt Busch, Murat Sivis, Christian Matyssek, Sergey V. Yalunin, Claus Ropers, T. Weber, S. Irsen, Felix von Cube

Publikováno v: 2015 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS).

Focusing light beyond the diffraction limit is of great interest in photonics. Metallic nano-tips offer the ability to concentrate light in nanometric volumes on femtosecond timescales, facilitating applications in tip-enhanced Raman scattering, opti

Real-space imaging of nanotip plasmons using electron energy loss spectroscopy

Autor: Thorsten Weber, Murat Sivis, Stephan Irsen, Sergey V. Yalunin, Christian Matyssek, Benjamin Schröder, Kurt Busch, Claus Roper, Felix von Cube, Sascha Schäfter, Thomas Kiel, Stefan Linden

Publikováno v: Physical Review B

We report the spatial mapping of surface plasmons on conical gold nanotips by electron energy loss spectroscopy. We observe standing-wave patterns resulting from reflections of the fundamental surface-plasmon mode at the nanotip apex. The experimenta

In situ observation of plasmon tuning in a single gold nanoparticle during controlled melting

Autor: Christian Matyssek, Stefan Schietinger, Kurt Busch, Oliver Benson, Alexander Kuhlicke

Publikováno v: Nano letters. 13(5)

In this Letter we study the relations among shape, symmetry, and plasmon resonance shift in a single gold nanoparticle during laser melting. A beam of an argon ion laser is focused on a selected particle, while its optical and shape properties can be
