Momentum microscopy of a holey nanostructure
Kerstin Harland, Julia Altenburg, Xiaofei Wu +10
Momentum microscopy records the three-dimensional momentum distribution of photoelectrons emitted from a solid sample and, by utilizing sufficiently high photon energies in the ult…
Momentum microscopy of ultrafast electron emission from a strongly driven optical nanoantenna
Kerstin Harland, Germann Hergert, Zsuzsanna Pápa +9
Metallic nanostructures in combination with femtosecond lasers are a well-suited platform for the control of photoelectrons by strong and nano-localized driving fields, with high r…
Spatially-resolved multiphoton photoemission from a lateral transition metal dichalcogenide heterostructure
Lina Hansen, Paul Martin, Sai Shradha +7
Transition metal dichalcogenides (TMDs) in their monolayer form offer a premier platform for next-generation optoelectronics, particularly through the local manipulation of their r…
Multiscale carrier-envelope phase characterization of 2-μm pulses delivered by a 200-kHz optical parametric amplifier
Katrin Meier, Arvid Klösgen, Kerstin Harland +7
Light fields with a central wavelength of 2 um are very well suited for strong-field-driven charge carrier control: Their photon energy lies far below the band gap of many material…
