Nanoscale Transport of Surface Excitons at the Interface between ZnO and a Molecular Monolayer
Sebastian Friede, Sergei Kuehn, Sergey Sadofev +3
Excitons play a key role for the optoelectronic properties of hybrid systems. We apply near-field scanning optical microscopy (NSOM) with a spatial resolution to…
Calculating optical absorption spectra of thin polycrystalline films: Structural disorder and site-dependent van der Waals interaction
Jörg Megow, Thomas Körzdörfer, Thomas Renger +4
We propose a new approach for calculating the change of the absorption spectrum of a molecule when moved from the gas phase to a crystalline morphology. The so-called gas-to-crysta…
Resonant interaction of molecular vibrations and surface plasmon polaritons: The weak coupling regime
S. Kalusniak, S. Sadofev, F. Henneberger
Adjusting the free-electron concentration, the surface plasmon frequency of the semiconductor ZnOGa is tuned into resonance with the molecular vibrations of the n-alkane tetraconta…
Space Charge Transfer in Hybrid Inorganic/Organic Systems
Yong Xu, Oliver T. Hofmann, Raphael Schlesinger +9
We discuss density functional theory calculations of hybrid inorganic/organic systems (HIOS) that explicitly include the global effects of doping (i.e. position of the Fermi level)…
Vertical cavity surface emitting laser action of an all monolithic ZnO-based microcavity
S. Kalusniak, S. Sadofev, S. Halm +1
We report on room temperature laser action of an all monolithic ZnO-based vertical cavity surface emitting laser (VCSEL) under optical pumping. The VCSEL structure consists of a 2λ…
Nonequilibrium nuclear-electron spin dynamics in semiconductor quantum dots
D. H. Feng, I. A. Akimov, F. Henneberger
We study the spin dynamics in charged quantum dots in the situation where the resident electron is coupled to only about 200 nuclear spins and where the electron spin splitting ind…
