Implementation and performance of a fiber-coupled CMOS camera in an ultrafast reflective high-energy electron diffraction experiment

Autor: Fortmann, Jonas D., Kaßen, Alexander, Brand, Christian, Duden, Thomas, Hoegen, Michael Horn-von

The implementation of a monolithic fiber-optically coupled CMOS-based TemCam-XF416 camera into our ultra-high vacuum (UHV) ultrafast reflection high-energy electron diffraction setup is reported. A combination of a pumpable gate valve and a self-buil

Disentangling the Electronic and Lattice Contributions to the Dielectric Response of Photoexcited Bismuth

Autor: Thiemann, Fabian, Sciaini, Germán, Kassen, Alexander, Lott, Tyler S., Hoegen, Michael Horn-von

Elucidating the interplay between nuclear and electronic degrees of freedom that govern the complex dielectric behavior of materials under intense photoexcitation is essential for tailoring optical properties on demand. However, conventional transien

Non-Equilibrium Pathways for Excitation of Bulk and Surface Phonons through Anharmonic Coupling

Autor: Brand, C., Tinnemann, V., Hanisch-Blicharski, A., Tajik, M., Fortmann, J. D., Kaßen, A., Thiemann, F., Hoegen, M. Horn-von

Upon impulsive optical excitation of solid-state materials, the non-equilibrium flow of energy from the excited electronic system to the lattice degrees of freedom typically happens in a few picoseconds. Here we identified the surface of thin Bi film
