Near-field enhancement by a metasurface at octupole plasmon resonance in periodic disc dimers
Sagar Sehrawat, Klas Lindfors, Andriy Shevchenko
Local intensity enhancement by plasmonic nanoparticles is widely used in optics and photonics. However, the effect is usually based on dipole resonances in the particles. Recently,…
Light-matter interaction between templated molecular layers and surface lattice resonances
Roland Schäfer, Manuel Neubauer, Klaus Meerholz +1
We couple a templated layer of merocyanine molecules with surface lattice resonances in a plasmonic grating. The templating of the molecular layer is achieved using a layer of alig…
Tunable photogating in a molecular aggregate coupled graphene phototransistor
Abhinav Raina, Maurizio Sanfilippo, Chang-Ki Moon +4
We present a graphene photodetector coupled to a layer of aggregated organic semiconductor. A graphene phototransistor is covered with a thin film of merocyanine molecules. The agg…
Polarization-controlled strong light-matter interaction with templated molecular aggregates
Roland Schäfer, Philipp Weitkamp, Otgonbayar Erdene-Ochir +2
We demonstrate strong light-matter interaction for a layer of templated merocyanine molecules in a planar microcavity. Using a single layer of graphene nanoribbons as a templating…
Influencing Optical and Charge Transport Properties by Controlling the Molecular Interactions of Merocyanine Thin Films
Lukas Böhner, Philipp Weitkamp, Thorsten Limböck +8
In organic semiconductors charge transport typically takes place via slow hopping processes. Molecular aggregation can lead to enhanced exciton and charge transport through couplin…
