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…

Highly coherent terahertz wave generation with a dual-frequency Brillouin fiber laser and a 1.55 μm photomixer

Guillaume Ducournau, P. Szriftgiser, Tahsin Akalin, Alexandre Beck, Denis Bacquet, Emilien Peytavit, Jean-Francois Lampin

Thanks to a portable dual-frequency Brillouin fiber laser and a 1.55 μm photomixer, we report the generation of a highly coherent kilohertz level submillimeter wave emission. Low-cost telecommunications components are used to achieve very simple source architecture. The photomixer is composed of a…

Co-integrated microfluidic and THz functions for biochip devices

Simon Laurette, A. Treizebre, Bertrand Bocquet

TeraHertz (THz) spectroscopy is becoming an alternative way to probe biological interactions in real-time conditions. However, accurate and reproducible THz measurements of aqueous solutions, largely represented in life sciences, remain difficult. A THz microsystem which couples both…

Growth rate model and doping metrology by atom probe tomography in silicon nanowire

W.H. Chen, R. Larde, E. Cadel, T. Xu, B. Grandidier, J.P. Nys, D. Stievenard, P. Pareige

Silicon nanowires (SiNWs) with different surface number density are fabricated using Chemical Vapor Deposition (CVD) method by controlling the catalyst droplet number density with in-situ evaporation. For comparison, another type of SiNWs is fabricated by Molecular Beam Epitaxy (MBE) method. To…

Giant magnetostrictive nanostructured films with auto induced spin reorientation transition

Yannick Dusch, Nicolas Tiercelin, A. Klimov, V. Rudenko, Y. Ignatov, S. Hage-Ali, Philippe Pernod, Vladimir Preobrazhensky

In various micro and nanosystems applications comprising magnetic films, the polarizing field still needs to be integrated. We hereby present a solution for self biasing of magnetic films using micropatterned permanent magnets. Micromagnetic simulations were used as a designing and optimization…
