Journal ArticleDOI
Oxidation mechanism of thin Cu films: A gateway towards the formation of single oxide phase
Sumita Choudhary,J. V. N. Sarma,Surojit Pande,Soraya Ababou-Girard,Pascal Turban,Bruno Lépine,Subhashis Gangopadhyay +6 more
TL;DR: In this paper, the authors investigated the role of the oxidation temperature, duration, oxygen partial pressure, film thickness and the crystallographic orientations in controlling the final phase of the copper oxide.
Journal ArticleDOI
Spin-polarized inelastic tunneling through insulating barriers.
Yuan Lu,Michael Tran,H. Jaffrès,Pierre Seneor,Cyrile Deranlot,Frédéric Petroff,J.-M. George,Bruno Lépine,S. Ababou,Guy Jézéquel +9 more
TL;DR: An extension of the Glazman-Matveev theory to the case of ferromagnetic reservoirs is proposed to account for spin-polarized inelastic tunneling through nonmagnetic localized states embedded in an insulating barrier.
Journal ArticleDOI
Solid state interdiffusions in epitaxial Fe/GaAs(001) heterostructures during ultrahigh vacuum annealings up to 450 °C
Bruno Lépine,S. Ababou,A. Guivarc'h,Guy Jézéquel,Stéphanie Députier,Roland Guérin,A. Filipe,Alain Schuhl,F. Abel,C. Cohen,André Rocher,J. Crestou +11 more
TL;DR: In this paper, a set of complementary experimental techniques were used to characterize an epitaxial structure (25 nm Fe)/GaAs(001) annealed at 450°C under ultrahigh vacuum conditions.
Journal ArticleDOI
Work function shifts, Schottky barrier height, and ionization potential determination of thin MgO films on Ag(001)
TL;DR: The electronic band structure and the work function of MgO thin films epitaxially grown on Ag(001) have been investigated using x-ray and ultraviolet photoelectron spectroscopy for various oxide thicknesses as discussed by the authors.
Journal ArticleDOI
Photoelectron spectroscopy study of Ga 3d and As 3d core levels on MBE-grown GaAs surfaces
M. Larive,Guy Jézéquel,J.P. Landesman,Francine Solal,J. Nagle,Bruno Lépine,A. Taleb-Ibrahimi,G. Indlekofer,X. Marcadet +8 more
TL;DR: In this paper, a photoemission study of GaAs MBE-grown surfaces, using UV radiation to investigate Ga 3D core levels (CLs) of (100) and (111)B surfaces in-situ, and using synchrotron radiation exsitu for the As 3d and the Ga 3d CLs study.
