Challenges in predicting positron annihilation lifetimes in lead halide perovskites: correlation functionals and polymorphism
Kajal Madaan, Guido Roma, Jasurbek Gulomov +3
Halide perovskites have emerged in the last decade as a new important class of semiconductors for a variety of optoelectronic applications. A lot of previous studies were thus devo…
Unraveling energy flow mechanisms in semiconductors by ultrafast spectroscopy: Germanium as a case study
Grazia Raciti, Begoña Abad, Riccardo Dettori +8
Semiconductor materials are the foundation of modern electronics, and their functionality is dictated by the interactions between fundamental excitations occurring on (sub-)picosec…
Sustainable wafer-scale integration of epitaxial ZnO on silicon for piezoelectric devices
D. Sanchez-Fuentes, R. Desgarceaux, A. Rahal +13
To sustainably support the ongoing energetic transition, we need functional metal oxides capable of converting energy, and produce storage, and sensing devices. However, these mate…
Relationship between polymorphic structures and magnetic properties of LaNi compounds (' = Sm, Gd)
Valérie Paul-Boncour, Véronique Charbonnier, Nicolas Madern +3
In this study, the crystal structure and magnetic properties of LaNi compounds with magnetic rare earth elements (' = Sm, Gd) have been investigated combini…
Grain-size dependence of plastic-brittle transgranular fracture
Jean-Michel Scherer, Mythreyi Ramesh, Blaise Bourdin +1
The role of grain size in determining fracture toughness in metals is incompletely understood with apparently contradictory experimental observations. We study this grain-size depe…
In-situ localization of damage in a Zn-Al-Mg coating deposited on steel by continuous hot-dip galvanizing
Houssem Eddine Chaieb, Vincent Maurel, Kais Ammar +6
Zn-Al-Mg coatings are characterized by a complex microstructure with dendritic and eutectic phases. This heterogeneous phase distribution contributes to multiple deformation and da…
