The influence of the binding energy on Compton-scattering-driven ionization
N. Melzer, M. Kircher, G. Kastirke +31
We present a comprehensive study of Compton scattering of 20 keV photons by bound electrons over a wide range of binding energies (Ne 2p, Ne 2s, C 1s, O 1s, and Ne 1s orbitals). In…
Phonon dynamics in Chromium under pressure: absence of phonon criticality at the approach of the quantum critical point
P. Rodière, J. E. Lorenzo, Q. N. Meier +2
Fermi surface nesting is key to understanding the origin of the itinerant antiferromagnetic spin density wave in chromium. This magnetic order is accompanied by a charge-density wa…
Epitaxial SiGeSn alloys for CMOS-compatible thermoelectric devices
Patrizio Graziosi, Damiano Marian, Andrea Tomadin +7
The integration of thermoelectric devices into mainstream microelectronic technological platform could be a major breakthrough in various fields within the \emph{so-called} Green-I…
Pressure-Induced Irreversible Disorder in -Mn(PO): A High-Pressure X-ray Diffraction and Density-Functional Theory Study
Ana Melissa P. Brito, Neha Bura, Pablo Botella +7
The high-pressure structural behavior of -Mn(PO) was investigated using synchrotron X-ray diffraction up to 20 GPa combined with density-functional theory cal…
High temperature ferromagnetism in epitaxial monolayers of Co-doped Fe5GeTe2
Jules Courtin, Fatima Ibrahim, Davide Benettin +14
Magnetic van der Waals materials have mainly been investigated in their bulk form or as few-layers flakes. Due to the challenges in producing atomically thin films, only a few have…
Low-spin ferrous iron suppresses mantle oxidation beyond Earth-like pressures
Alice Girani, Sylvain Petitgirard, Sergey Yaroslavstsev +5
The Earth's mantle has elevated Fe relative to those of other rocky bodies, yet the oxidation- and electronic state of iron at extreme pressures is poorly known. We present…
