Spectroscopic mapping of local structural distortions in ferroelectric PbTiO3/SrTiO3 superlattices at the unit-cell scale
Almudena Torres-Pardo, Alexandre Gloter, Pavlo Zubko +5
The local structural distortions in polydomain ferroelectric PbTiO3/SrTiO3 superlattices are investigated by means of high spatial and energy resolution electron energy loss spectr…
Coherent Phonon Coupling to Individual Bloch States in Photoexcited Bismuth
E. Papalazarou, J. Faure, J. Mauchain +8
We investigate the temporal evolution of the electronic states at the bismuth (111) surface by means of time and angle resolved photoelectron spectroscopy. The binding energy of bu…
Investigation of the thermal stability of Mg/Co periodic multilayers for EUV applications
M. -H. Hu, K. Le Guen, Jean-Michel André +11
We present the results of the characterization of Mg/Co periodic multilayers and their thermal stability for the EUV range. The annealing study is performed up to a temperature of…
Density-Functional Theory Study of Hydrogen Induced Platelets (HIPs) in Silicon
Liviu Bîlteanu, Jean-Paul Crocombette
In this contribution we present the results of Density-Functional Theory (DFT) calculations of platelets as modelled by infinite planar arrangements of hydrogen atoms and vacancies…
Hydrogen Diffusion in Silicon - An ab initio Study of Hydrogen Kinetic Properties in Silicon
Liviu Bilteanu, Mathias Posselt, Jean-Paul Crocombette
In this paper we present kinetic properties such as migration and decomposition barriers of hydrogen defects in silicon calculated by Density Functional Theory (DFT) based methods.…
Low energy graphene edge termination via small diameter nanotube formation
Viktoria V. Ivanovskaya, Alberto Zobelli, Philipp Wagner +4
We demonstrate that free graphene sheet edges can curl back on themselves,reconstructing as nanotubes. This results in lower formation energies than any other non-functionalised ed…
Identification and selection rules of the spin-wave eigen-modes in a normally magnetized nano-pillar
Vladimir V. Naletov, Grégoire De Loubens, Gonçalo Albuquerque +12
We report on a spectroscopic study of the spin-wave eigen-modes inside an individual normally magnetized two layers circular nano-pillar (PermalloyCopperPermalloy) by means o…
Model of bound interface dynamics for coupled magnetic domain walls
P. Politi, P. J. Metaxas, J. -P. Jamet +2
A domain wall in a ferromagnetic system will move under the action of an external magnetic field. Ultrathin Co layers sandwiched between Pt have been shown to be a suitable experim…
Field-induced domain wall propagation: beyond the one-dimensional model
L. Thevenard, C. Gourdon, S. Haghgoo +5
We have investigated numerically the field-driven propagation of perpendicularly magnetized ferromagnetic layers. It was then compared to the historical one-dimensional domain wall…
Asymmetric pulsing for reliable operation of titanium/manganite memristors
F. Gomez-Marlasca, N. Ghenzi, P. Stoliar +4
We present a pulsing protocol that significantly increases the endurance of a titanium-manganite interface used as a binary memory cell. The core of this protocol is an algorithm t…
Metal-insulator transition in ultrathin LaNiO3 films
R. Scherwitzl, S. Gariglio, M. Gabay +3
Transport in ultrathin films of LaNiO3 evolves from a metallic to a strongly localized character as the film's thickness is reduced and the sheet resistance reaches a value close t…
