Generation of ultrashort keV Ar+ ion pulses via femtosecond laser photoionization

Autor: Alexander Golombek, Lars Breuer, Lisa Danzig, Paul Kucharczyk, Marika Schleberger, Klaus Sokolowski-Tinten, Andreas Wucher

Publikováno v: New Journal of Physics, Vol 23, Iss 3, p 033023 (2021)

Ion beams with energies in the keV regime are widely utilized in solid-state physics, but the ultrafast dynamics triggered by an ion impact onto a solid surface is to date exclusively accessible via simulations based on many untested assumptions and

Structural changes across thermodynamic maxima in supercooled liquid tellurium: A water-like scenario

Autor: Peihao Sun, Giulio Monaco, Peter Zalden, Klaus Sokolowski-Tinten, Jerzy Antonowicz, Ryszard Sobierajski, Yukio Kajihara, Alfred Q. R. Baron, Paul Fuoss, Andrew Chihpin Chuang, Jun-Sang Park, Jonathan Almer, J. B. Hastings

Liquid polymorphism is an intriguing phenomenon which has been found in a few single-component systems, the most famous being water. By supercooling liquid Te to more than 130 K below its melting point and performing simultaneous small-angle and wide

Fast attenuation of high-frequency acoustic waves in bicontinuous nanoporous gold

Autor: Qiang Zheng, Jie Yang, Mianzhen Mo, Takeshi Fujita, Xiaozhe Shen, Zhijiang Chen, Y. Tian, Xijie Wang, Mingwei Chen, Pan Liu, Klaus Sokolowski-Tinten, Zhili Wang, Stephen Weathersby, Renkai Li

We studied the formation and attenuation of GHz elastic waves in free-standing nanoporous gold films by MeV ultrafast electron diffraction and finite element simulations. By tracing the evolution of the high frequency acoustic waves in time domain, w

Time-resolved diffraction with an optimized short pulse laser plasma X-ray source

Autor: Mohammadmahdi Afshari, Philipp Krumey, Klaus Sokolowski-Tinten, Dennis Menn, Matthieu Nicoul, Fabian Brinks, Alexander Tarasevitch

Publikováno v: Structural Dynamics
Structural Dynamics, Vol 7, Iss 1, Pp 014301-014301-11 (2020)

We present a set-up for time-resolved X-ray diffraction based on a short pulse, laser-driven plasma X-ray source. The employed modular design provides high flexibility to adapt the set-up to the specific requirements (e.g. X-ray optics, sample enviro

Effect of lattice excitations on transient near edge X-ray absorption spectroscopy

Publikováno v: Physical review / B 104(14), 144302 (2021). doi:10.1103/PhysRevB.104.144302

Time-dependent and constituent-specific spectral changes in soft near edge X-ray spectroscopy (XAS) of an [Fe/MgO]$_8$ metal/insulator heterostructure upon laser excitation are analyzed at the O K-edge with picosecond time resolution. The oxygen abso

Tracking the Ultrafast Non-Equilibrium Energy Flow between Electronic and Lattice Degrees of Freedom in Crystalline Nickel

Autor: Karel Carva, Pablo Maldonado, Hermann A. Dürr, Xiaozhe Shen, Klaus Sokolowski-Tinten, Xijie Wang, Peter M. Oppeneer, T. Payer, M. Horn-von Hoegen, Renkai Li, Alexander H. Reid, T. Chase

Femtosecond laser excitation of solid-state systems creates out-of-equilibrium hot electrons that cool down by transferring their energy to other degrees of freedom and ultimately to lattice vibrations of the solid. By combining ab initio calculation

6 pags., 5 figs.
In phase-change memory devices, a material is cycled between glassy and crystalline states. The highly temperature-dependent kinetics of its crystallization process enables application in memory technology, but the transition ha
