Nanoscale origin of thermal anisotropy in monoclinic \texorpdfstring{-GaO}{beta-Ga2O3}
Kai Xu, Shuo Zhao, Luca Sung-Min Choi +19
Monoclinic -GaO is a promising ultra-wide-bandgap semiconductor for power electronics, but its low and anisotropic thermal conductivity limits heat removal, making it a…
X-ray driven displacive excitation of coherent phonons
Oleg Dogadov, Remi Claude, Christoph Emeis +29
Modulating electron-phonon coupling offers a route to control structural displacements and tune material functionality. Valence-to-conduction band transitions, however, provide lim…
Impact of a monolayer on the nanoscale thermoelastic response of silicon heterostructures
Davide Soranzio, Denny Puntel, Manuel Tuniz +18
Understanding the thermoelastic response of a nanostructure is crucial for the choice of materials and interfaces in electronic devices with improved and tailored transport propert…
Transient grating spectroscopy on a DyCo thin film with femtosecond extreme ultraviolet pulses
Victor Ukleev, Ludmila Leroy, Riccardo Mincigrucci +11
Surface acoustic waves (SAWs) are excited by femtosecond extreme ultraviolet (EUV) transient gratings (TGs) in a room-temperature ferrimagnetic DyCo alloy. TGs are generated by…
Nanoscale transient polarization gratings
Laura Foglia, Björn Wehinger, Giovanni Perosa +24
We present the generation of transient polarization gratings at the nanoscale, achieved using a tailored accelerator configuration of the FERMI free electron laser. We demonstrate…
FEL stochastic spectroscopy revealing silicon bond softening dynamics
Dario De Angelis, Emiliano Principi, Filippo Bencivenga +20
Time-resolved X-ray Emission/Absorption Spectroscopy (Tr-XES/XAS) is an informative experimental tool sensitive to electronic dynamics in materials, widely exploited in diverse res…
Extreme ultraviolet transient gratings: A tool for nanoscale photoacoustics
L. Foglia, R. Mincigrucci, A. A. Maznev +23
Collective lattice dynamics determine essential aspects of condensed matter, such as elastic and thermal properties. These exhibit strong dependence on the length-scale, reflecting…
All-optical switching on the nanometer scale excited and probed with femtosecond extreme ultraviolet pulses
Kelvin Yao, Felix Steinbach, Martin Borchert +13
Ultrafast control of magnetization on the nanometer length scale, in particular all-optical switching, is key to putting ultrafast magnetism on the path towards future technologica…
Ultrafast dynamics in (TaSe)I triggered by valence and core-level excitation
Wibke Bronsch, Manuel Tuniz, Giuseppe Crupi +16
In this work, we study the out-of-equilibrium dynamics of the paradigmatic quasi-one-dimensional material (TaSe)I, that exhibits a transition into an incommensurate CDW pha…
Ångström-resolved Interfacial Structure in Organic-Inorganic Junctions
Craig P. Schwartz, Sumana L. Raj, Sasawat Jamnuch +18
Charge transport processes at interfaces which are governed by complex interfacial electronic structure play a crucial role in catalytic reactions, energy storage, photovoltaics, a…
