Spatio-temporal coupling of attosecond pulses
Hampus Wikmark, Chen Guo, Jan Vogelsang +12
The shortest light pulses produced to date are of the order of a few tens of attoseconds, with central frequencies in the extreme ultraviolet range and bandwidths exceeding tens of…
Determining the True Optical Gap in a High-Performance Organic Photovoltaic Polymer Using Single-Molecule Spectroscopy
Gordon J. Hedley, Florian Steiner, Jan Vogelsang +1
Low-gap conjugated polymers have enabled an impressive increase in the efficiencies of organic solar cells, primarily due to their red absorption which allows harvesting of that pa…
Role of Triplet-State Shelving in Organic Photovoltaics: Single-Chain Aggregates of Poly(3-hexylthiophene) versus Mesoscopic Multichain Aggregates
Florian Steiner, John M. Lupton, Jan Vogelsang
Triplet excitons have been the focus of considerable attention with regards to the functioning of polymer solar cells, because these species are long-lived and quench subsequently…
Watching charge separation in nanoantennas by ultrafast point-projection electron microscopy
Jan Vogelsang, Germann Hergert, Dong Wang +2
Watching the motion of electrons on their natural nanometre length- and femtosecond time scales is a fundamental goal and an open challenge of contemporary ultrafast science. Optic…
