Conduction Band Structure and Ultrafast Dynamics of Ferroelectric -GeTe(111)
Geoffroy Kremer, Laurent Nicolaï, Frédéric Chassot +9
-GeTe(111) is a non-centrosymmetric ferroelectric (FE) material for which a significative lattice distortion combined with a strong spin-orbit interaction gives rise to giant Ra…
Energy-efficient picosecond spin-orbit torque magnetization switching in ferro- and ferrimagnetic films
Eva Díaz, Alberto Anadón, Pablo Olleros-Rodríguez +7
Electrical current pulses can be used to manipulate magnetization efficiently via spin-orbit torques (SOTs). Pulse durations as short as a few picoseconds have been used to switch…
High-quality hexagonal boron nitride selectively grown on patterned epigraphene by MOVPE
Vishnu Ottapilakkal, Abhishek Juyal, Suresh Sundaram +14
Hexagonal boron nitride encapsulation is the method of choice for protecting graphene from environmental doping and impurity scattering. It was previously demonstrated that metal-o…
Influence of surface pre-deformation on the Portevin-Le Chatelier effect and the related multiscale complexity of plastic flow in an Al-Mg alloy
Hafsa Jaber, Benoît Beausir, Denis Entemeyer +3
The influence of the surface pre-deformation on jerky flow caused by the Portevin-Le Chatelier (PLC) effect was investigated using flat tensile specimens of an Al-Mg alloy. Althoug…
Bonding states underpinning structural transitions in IrTe observed with micro-ARPES
C. W. Nicholson, M. D. Watson, A. Pulkkinen +6
Competing interactions in low-dimensional materials can produce nearly degenerate electronic and structural phases. We investigate the staircase of structural phase transitions in…
Van der Waals epitaxy of Weyl-semimetal Td-WTe
Alexandre Llopez, Frédéric Leroy, Calvin Tagne-Kaegom +13
Epitaxial growth of WTe offers significant advantages, including the production of high-qualityfilms, possible long range in-plane ordering and precise control over layer thick…
