Direct measurement of key exciton properties: energy, dynamics and spatial distribution of the wave function
Shuo Dong, Michele Puppin, Tommaso Pincelli +15
Excitons, Coulomb-bound electron-hole pairs, are the fundamental excitations governing the optoelectronic properties of semiconductors. While optical signatures of excitons have be…
Ultrafast lattice dynamics and electron-phonon coupling in platinum extracted with a global fitting approach for time-resolved polycrystalline diffraction data
Daniela Zahn, Hélène Seiler, Yoav William Windsor +1
Quantitative knowledge of electron-phonon coupling is important for many applications as well as for the fundamental understanding of nonequilibrium relaxation processes. Time-reso…
Nuclear dynamics of singlet exciton fission: a direct observation in pentacene single crystals
Hélène Seiler, Marcin Krynski, Daniela Zahn +7
Singlet exciton fission (SEF) is a key process in the development of efficient opto-electronic devices. An aspect that is rarely probed directly, and yet has a tremendous impact on…
A quantitative comparison of time-of-flight momentum microscopes and hemispherical analyzers for time- and angle-resolved photoemission spectroscopy experiments
J. Maklar, S. Dong, S. Beaulieu +7
Time-of-flight-based momentum microscopy has a growing presence in photoemission studies, as it enables parallel energy- and momentum-resolved acquisition of the full photoelectron…
Accessing the anisotropic non-thermal phonon populations in black phosphorus
Hélène Seiler, Daniela Zahn, Marios Zacharias +8
We combine femtosecond electron diffuse scattering experiments and first-principles calculations of the coupled electron-phonon dynamics to provide a detailed momentum-resolved pic…
Soft x-ray absorption of thin films detected using substrate luminescence: A performance analysis
Cinthia Piamonteze, Yoav William Windsor, Sridhar R. V. Avula +2
X-ray absorption spectroscopy of thin films is central to a broad range of scientific fields, and is typically detected using indirect techniques. X-ray excited optical luminescenc…
Anisotropic Nonequilibrium Lattice Dynamics of Black Phosphorus
Daniela Zahn, Patrick-Nigel Hildebrandt, Thomas Vasileiadis +4
Black phosphorus has recently attracted significant attention for its highly anisotropic properties. A variety of ultrafast optical spectroscopies has been applied to probe the car…
