X-ray diffraction reveals the consequences of strong deformation in thin smectic films: dilation and chevron formation
Jean de Dieu Niyonzima, Haifa Jeridi, Lamya Essaoui +14
Smectic liquid crystals can be viewed as model systems for lamellar structures for which there has been extensive theoretical development. We demonstrate that a nonlinear energy de…
Structure of germanene/Al(111): a two-layers surface alloy
K. Zhang, D. Sciacca, M. -C. Hanf +12
Unlike silicene, for which the demonstration of its existence has been done through numerous independent studies, the possibility of growing epitaxial germanene remains highly cont…
Resolving the structure of the striped Ge layer on Ag(111): AgGe surface alloy with alternate fcc and hcp domains
K. Zhang, D. Sciacca, A. Coati +8
Two-dimensional (2D) honeycomb lattices beyond graphene, such as germanene, promise new physical properties such as quantum spin Hall effect. While there have been many claims of g…
A convolutional neural network for defect classification in Bragg coherent X-ray diffraction
Bruce Lim, Ewen Bellec, Maxime Dupraz +8
Coherent diffraction imaging enables the imaging of individual defects, such as dislocations or stacking faults, in materials.These defects and their surrounding elastic strain fie…
Gas-induced selective re-orientation of Au-Cu nanoparticles on TiO 2 (110)
Axel Wilson, Aude Bailly, Romain Bernard +11
Au-Cu bimetallic nanoparticles (NPs) grown on TiO 2 (110) have been followed in-situ using grazing incidence x-ray diffraction and x-ray photoemission spectroscopy from their synth…
Co/Ni multilayers for spintronics: high spin-polarization and tunable magnetic anisotropy
S. Andrieu, T. Hauet, M. Gottwald +13
In this paper we analyze in details the electronic properties of (Co/Ni) multilayers, a model system for spintronics devices. We use magneto-optical Kerr (MOKE), spin-polarized pho…
Wide bandgap semiconductor from a hidden 2D incommensurate graphene phase
Matthew Conrad, Feng Wang, Meredith Nevius +10
Producing a usable semiconducting form of graphene has plagued the development of graphene electronics for nearly two decades. Now that new preparation methods have become availabl…
Symmetry of the Fermi surface and evolution of the electronic structure across the paramagnetic-helimagnetic transition in MnSi/Si(111)
Alessandro Nicolaou, Matteo Gatti, Elena Magnano +11
MnSi has been extensively studied for five decades, nonetheless detailed information on the Fermi surface (FS) symmetry is still lacking. This missed information prevented from a c…
