Spot Profile Analysis Low Energy Electron Diffraction of Plasma-Enhanced Chemical Vapor Deposition Grown Epitaxial Few-Layer Graphene on Sapphire
Niels Ganser, Marko A. Kriegel, Umut Kaya +6
We demonstrate the use of high-resolution spot-profile analysis low-energy electron diffraction to determine the mean grain size of plasma-enhanced chemical vapor deposition grown…
A Two-Step Chemical Vapor Deposition Process for the Synthesis of an Ir(111)/Borophene/2D-Hexagonal Boron Nitride Heterostructure by Intrinsic Segregation
Marko A. Kriegel, Karim M. Omambac, Smruti R. Mohanty +10
We report on a two-step ultrahigh vacuum chemical vapor deposition synthesis of a vertical Ir(111)/borophene/hexagonal boron nitride heterostructure, using borazine as a single-sou…
Disentangling the Electronic and Lattice Contributions to the Dielectric Response of Photoexcited Bismuth
Fabian Thiemann, Germán Sciaini, Alexander Kassen +2
Elucidating the interplay between nuclear and electronic degrees of freedom that govern the complex dielectric behavior of materials under intense photoexcitation is essential for…
A modular table-top setup for ultrafast X-ray diffraction
Wei Lu, Matthieu Nicoul, Uladzimir Shymanovich +4
We present a table-top setup for femtosecond time-resolved X-ray diffraction based on a Cu Kα (8.05 keV) laser driven plasma X-ray source. Due to its modular design it provides hig…
Ultrafast transport mediated homogenization of photoexcited electrons governs the softening of the phonon in bismuth
Fabian Thiemann, Germán Sciaini, Alexander Kassen +3
In order to determine the role of non-thermal transport of hot carriers which is decisive for the dissipation of energy in condensed matter we performed time-resolved broadband fem…
Tracking the Ultrafast Non-Equilibrium Energy Flow between Electronic and Lattice Degrees of Freedom in Crystalline Nickel
P. Maldonado, T. Chase, A. H. Reid +9
Femtosecond laser excitation of solid-state systems creates non-equilibrium hot electrons that cool down by transferring their energy to other degrees of freedom and ultimately to…
