Journal ArticleDOI
Unravelling the role of the interface for spin injection into organic semiconductors
Clément Barraud,Pierre Seneor,Richard Mattana,Stéphane Fusil,Stéphane Fusil,Karim Bouzehouane,Cyrile Deranlot,Patrizio Graziosi,Luis E. Hueso,Ilaria Bergenti,Valentin Dediu,Frédéric Petroff,Albert Fert +12 more
TL;DR: In this paper, the metal/organic interface is found to be key for spin injection in organic semiconductors, and the authors investigated how to optimize the injection of spin into these materials.
Journal ArticleDOI
Room-temperature spintronic effects in Alq3-based hybrid devices
Valentin Dediu,Luis E. Hueso,Ilaria Bergenti,Alberto Riminucci,Francesco Borgatti,Patrizio Graziosi,Carol Newby,Francesca Casoli,M. P. de Jong,C. Taliani,Yiqiang Zhan +10 more
TL;DR: In this paper, vertical spin valve devices with a direct interface between the bottom manganite electrode and Alq3, while the top-electrode geometry consists of an insulating tunnel barrier placed between the soft organic semiconductor and the top Co electrode.
Journal ArticleDOI
Electrically programmable magnetoresistance in multifunctional organic-based spin valve devices.
Mirko Prezioso,Alberto Riminucci,Ilaria Bergenti,Patrizio Graziosi,David Brunel,Valentin Dediu +5 more
TL;DR: It is shown that an electrically controlled magne-toresistance can be easily achieved in organic devices by com-bining magnetic bistability (spin valve) and electrical memory effects into an interacting multifunctional implementation.
Journal ArticleDOI
A Single‐Device Universal Logic Gate Based on a Magnetically Enhanced Memristor
Mirko Prezioso,Alberto Riminucci,Patrizio Graziosi,Ilaria Bergenti,R. K. Rakshit,Raimondo Cecchini,Anna Vianelli,Francesco Borgatti,Norman Haag,Maureen Willis,Alan J. Drew,William P. Gillin,Valentin Dediu +12 more
TL;DR: Two experimental proofs of concept are presented based on the intermixing of spintronic and memristive effects into a single device, a magnetically enhanced memristor (MEM), which realizes a universal implication (IMP) logic gate based on a single MEM device.
Journal ArticleDOI
The role of aluminum oxide buffer layer in organic spin-valves performance
Yiqiang Zhan,Xianjie Liu,Elin Carlegrim,Fenghong Li,Ilaria Bergenti,Patrizio Graziosi,Valentin Dediu,Mats Fahlman +7 more
TL;DR: The electronic structures of the 8-hydroxyquinoline-aluminum (Alq(3))/Al2O3/Co interfaces were studied by photoelectron spectroscopy.
