Electron Imaging of Nanoscale Charge Distributions Induced by Femtosecond Light Pulses
Jonathan T. Weber, Sascha Schäfer
Surface charging is a phenomenon ubiquitously observable in in-situ transmission electron microscopy of non-conducting specimens as a result of electron beam/sample interactions or…
Phase-ordering of charge density waves traced by ultrafast low-energy electron diffraction
S. Vogelgesang, G. Storeck, S. Schramm +3
We introduce ultrafast low-energy electron diffraction (ULEED) in backscattering for the study of structural dynamics at surfaces. Using a tip-based source of ultrashort electron p…
Ultrafast transmission electron microscopy using a laser-driven field emitter: femtosecond resolution with a high coherence electron beam
Armin Feist, Nora Bach, Nara Rubiano da Silva +12
We present the development of the first ultrafast transmission electron microscope (UTEM) driven by localized photoemission from a field emitter cathode. We describe the implementa…
A light induced metastable magnetic texture uncovered by in-situ Lorentz microscopy
Tim Eggebrecht, Marcel Möller, J. Gregor Gatzmann +7
Magnetic topological defects, including vortices and Skyrmions, can be stabilized as equilibrium structures by tuning intrinsic magnetic interactions and stray field geometries. He…
Kondo physics and orbital degeneracy interact to boost thermoelectrics on the nanoscale
J. Azema, A. -M. Daré, S. Schäfer +1
We investigate the transport through a nanoscale device consisting of a degenerate double-orbital Anderson dot coupled to two uncorrelated leads. We determine the thermoelectric tr…
