Since the discovery of electron-wave duality, electron scattering instrumentation has
developed into a powerful array of techniques for revealing the atomic structure of matter …

The advent of pump-probe spectroscopy techniques paved the way to the exploration of
ultrafast dynamics of electrons and phonons in crystalline solids. Following photo-absorption …

The electron-phonon coupling and the corresponding energy exchange are investigated
experimentally and by ab initio theory in nonequilibrium states of the free-electron metal …

Femtosecond resolution electron scattering techniques are applied to resolve the first atomic-
scale steps following absorption of a photon in the prototypical hybrid perovskite …

Transition-metal dichalcogenide monolayers and heterostructures are highly tunable
material systems that provide excellent models for physical phenomena at the two …

Phonon scattering in metals is one of the most fundamental processes in materials science.
However, understanding such processes has remained challenging and requires detailed …

Ultrafast laser excitation of a metal causes correlated, highly nonequilibrium dynamics of
electronic and ionic degrees of freedom, which are, however, only poorly captured by the …

In the prevalent picture of ultrafast structural phase transitions, atomic motion occurs in a
slowly varying potential energy surface adiabatically determined by fast electrons. However …

We investigate the interactions of photoexcited carriers with lattice vibrations in thin films of
the layered transition metal dichalcogenide (TMDC) WSe 2. Employing femtosecond …

We report the design and performance of a time-resolved electron diffraction apparatus
capable of producing intense bunches with simultaneously single digit micrometer probe …
