Spin-dependent photoelectron tunneling from GaAs into magnetic cobalt

D. Vu, H. Jurca, F. Maroun, P. Allongue, N. Tournerie, A. Rowe, D. Paget, S. Arscott, Emilien Peytavit

The spin dependence of the photoelectron tunnel current from free standing GaAs films into outof-plane magnetized Cobalt films is demonstrated. The measured spin asymmetry (A) resulting from a change in light helicity, reaches ±6% around zero applied tunnel bias and drops to ±2% at a bias of -1.6 V…

Asymmetry of polarization reversal and current-voltage characteristics of Pt/PZT-Film/Pt:Ti/SiO2/Si-substrate structures

S.L. Bravina, N.V. Morozovsky, J. Costecalde, Caroline Soyer, Denis Remiens, D. Deresmes

The characterization of the asymmetries of bipolar charge-voltage and current-voltage loops of polarization reversal and unipolar current-voltage curves for Pt/PZT-film/Pt:Ti/SiO2/Si-substrate systems was performed in the dynamic mode. The asymmetry of local deformation-voltage loops was observed…

Exploit the bandwidth capacities of the perfluorinated graded index polymer optical fiber for multi-services distribution

C. Lethien, Christophe Loyez, Jean-Pierre Vilcot, N. Rolland, P.A. Rolland

The study reported here deals with the exploitation of perfluorinated graded index polymer optical fiber bandwidth to add further services in a home/office network. The fiber properties are exhibited in order to check if perfluorinated graded index plastic optical fiber (PFGI-POF) is suitable to…

Optimization of ohmic contact and adhesion on polysilicon in MEMS–NEMS wet etching process

Etienne Herth, Emmanuelle Algré, Bernard Legrand, Lionel Buchaillot

This paper presents the optimization of polysilicon doping and metallization to form ohmic contact with etching resistance. Indeed, polysilicon doped by ion implantation and ohmic contacts are an important and interesting part of integrated circuit technology or MEMS and NEMS. LPCVD-polysilicon…

Thickness effect on nanoscale electromechanical activity in Pb(Mg1/3Nb2/3)O3-PbTiO3 thin films studied by piezoresponse force microscopy

A. Ferri, M. Detalle, J.F. Blach, M. Warenghem, Denis Remiens, R. Desfeux

0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3 (PMN–PT) ferroelectric thin films with thickness ranging from 28 to 110 nm were sputter deposited onto LaNiO3/SiO2/Si substrates. Optical properties were determined by spectroscopic ellipsometry. We found B = 4.6 and λ0 = 209 nm, which is consistent for all PMN–PT…

Magnetoelectric memory using perpendicular magnetization states and magnetoelastic switching

Nicolas Tiercelin, Yannick Dusch, V.L. Preobrazhensky, Philippe Pernod

We present here a concept of a memory cell called MELRAM based on a magnetic element with giant magnetostriction, embedded in a piezoelectric matrix. Two equilibrium orientations of magnetization are defined by combining uniaxial anisotropy together with a magnetic polarization in the hard axis…
