Direct visualization of polaron formation in the thermoelectric SnSe
Laurent P. René de Cotret, Martin R. Otto, Jan-Hendrick Pöhls +3
SnSe is a layered material that currently holds the record for bulk thermoelectric efficiency. The primary determinant of this high efficiency is thought to be the anomalously low…
Mechanisms of electron-phonon coupling unraveled in momentum and time: The case of soft-phonons in TiSe
Martin R. Otto, Jan-Hendrik Pöhls, Laurent P. René de Cotret +3
The complex coupling between charge carriers and phonons is responsible for diverse phenomena in condensed matter. We apply ultrafast electron diffuse scattering to unravel electro…
Mapping momentum-dependent electron-phonon coupling and non-equilibrium phonon dynamics with ultrafast electron diffuse scattering
Mark J. Stern, Laurent P. René de Cotret, Martin R. Otto +4
Despite their fundamental role in determining material properties, detailed momentum-dependent information on the strength of electron-phonon and phonon-phonon coupling (EPC and PP…
Solving the Jitter Problem in Microwave Compressed Ultrafast Electron Diffraction Instruments: Robust Sub-50 fs Cavity-Laser Phase Stabilization
Martin R. Otto, Laurent P. Rene de Cotret, Mark J. Stern +1
We demonstrate the compression of electron pulses in a high-brightness ultrafast electron diffraction (UED) instrument using phase-locked microwave signals directly generated from…
