Time-domain extreme ultraviolet diffuse scattering spectroscopy of nanoscale surface phonons
F. Capotondi, A. Maznev, F. Bencivenga +18
We report the observation of dynamic fringe patterns in the diffuse scattering of extreme ultraviolet light from surfaces, following femtosecond optical excitation. At each point o…

Formalism to Image the Dynamics of Coherent and Incoherent Phonon with Dark-Field X-ray Microscopy using Kinematic Diffraction Theory
Darshan Chalise, Yifan Wang, Mariano Trigo +1
Dark-field X-ray microscopy (DFXM) is a novel X-ray imaging technique developed at synchrotrons to image along the diffracted beam with a real space resolution of ~100 nm and recip…
