Journal ArticleDOI
A ferroelectric memristor
André Chanthbouala,Vincent Garcia,Ryan O. Cherifi,Karim Bouzehouane,Stéphane Fusil,Stéphane Fusil,Xavier Moya,Stéphane Xavier,Hiroyuki Yamada,Hiroyuki Yamada,Cyrile Deranlot,Neil D. Mathur,Manuel Bibes,Agnès Barthélémy,Julie Grollier +14 more
TL;DR: It is demonstrated that voltage-controlled domain configurations in ferroelectric tunnel barriers yield memristive behaviour with resistance variations exceeding two orders of magnitude and a 10 ns operation speed.
Journal ArticleDOI
Solid-state memories based on ferroelectric tunnel junctions
André Chanthbouala,A. Crassous,Vincent Garcia,Karim Bouzehouane,Stéphane Fusil,Stéphane Fusil,Xavier Moya,J. Allibe,Bruno Dlubak,Julie Grollier,Stéphane Xavier,Cyrile Deranlot,Amir Moshar,Roger Proksch,Neil D. Mathur,Manuel Bibes,Agnès Barthélémy +16 more
TL;DR: Non-volatile memories with OFF/ON ratios as high as 100 and write powers as low as ∼1 × 10(4) A cm(-2) at room temperature are reported by storing data in the electric polarization direction of a ferroelectric tunnel barrier.
Journal ArticleDOI
Learning through ferroelectric domain dynamics in solid-state synapses.
Sören Boyn,Sören Boyn,Julie Grollier,Gwendal Lecerf,Bin Xu,Nicolas Locatelli,Stéphane Fusil,Stéphanie Girod,Stéphanie Girod,C. Carrétéro,Karin Garcia,Stéphane Xavier,Jean Tomas,Laurent Bellaiche,Manuel Bibes,Agnès Barthélémy,Sylvain Saïghi,Vincent Garcia +17 more
TL;DR: This work reports on synapses based on ferroelectric tunnel junctions and shows that STDP can be harnessed from inhomogeneous polarization switching and demonstrates that conductance variations can be modelled by the nucleation-dominated reversal of domains.
Journal ArticleDOI
Highly efficient spin transport in epitaxial graphene on SiC
Bruno Dlubak,Marie-Blandine Martin,Cyrile Deranlot,Bernard Servet,Stéphane Xavier,Richard Mattana,Mike Sprinkle,Claire Berger,Claire Berger,Walt A. de Heer,Frédéric Petroff,Abdelmadjid Anane,Pierre Seneor,Albert Fert +13 more
TL;DR: A demonstration of the ability to transmit spin currents over distances of more than one hundred micrometres with an efficiency of up to 75% in graphene grown epitaxially on silicon carbide improves the prospects of graphene-based spintronic devices.
Journal ArticleDOI
Antifogging abilities of model nanotextures
Timothée Mouterde,Gaëlle Lehoucq,Stéphane Xavier,Antonio Checco,Charles T. Black,Atikur Rahman,Thierry Midavaine,Christophe Clanet,Christophe Clanet,David Quéré,David Quéré +10 more
TL;DR: This work investigates the underlying antifogging mechanism in model materials designed to mimic natural systems, and explains the importance of the texture's feature size and shape.
