Atomic Scale Observation of Chemical and Electronic Properties of Metal-Oxide Surfaces

To meet the future global energy demand - an estimated additional 10 terawatts (TWs) per year in 2050 - a diversification of energy sources and fuels is needed. Solar energy represents a prominent alternative energy source. An important material for these ...

Atomic-Scale Observation of Multiconformational Binding and Energy Level Alignment of Ruthenium-Based Photosensitizers on TiO2 Anatase

Klaus Kern, Christian Alexander Stephan Dette, Stephan Rauschenbach, Sebastian Stepanow, Feliciano Giustino, Gordon Rinke, Christopher Seiji Kley

Dye-sensitized solar cells constitute a promising approach to sustainable and low-cost solar energy conversion. Their overall efficiency crucially depends on the effective coupling of the photosensitizers to the photoelectrode and the details of the dye's ...

TiO2 Anatase with a Bandgap in the Visible Region

Klaus Kern, Christian Alexander Stephan Dette, Feliciano Giustino, Christopher Seiji Kley

TiO2 anatase plays a central role in energy and environmental research. A major bottleneck toward developing artificial photosynthesis with TiO2 is that it only absorbs ultraviolet light, owing to its large bandgap of 3.2 eV. If one could reduce the bandga ...

Molecular Orbital Gates for Plasmon Excitation

Klaus Kern, Uta Schlickum, Christian Alexander Stephan Dette, Theresa Lutz, Christoph Grosse, Alexander Kabakchiev

Future combinations of plasmonics with nanometer-size electronic circuits require strategies to control the electrical excitation of plasmons at the length scale of individual molecules. A unique tool to study the electrical plasmon excitation with ultimat ...
