Anisotropic excitonic effects in the energy loss function of hexagonal boron nitride

S. Galambosi, L. Wirtz, J.A. Soininen, J. Serrano, A. Marini, K. Watanabe, T. Taniguchi, S. Huotari, A. Rubio, K. Hamalainen

The anisotropy of the valence energy-loss function of hexagonal boron nitride (hBN) is shown to be largely enhanced by the highly inhomogeneous character of the excitonic states. The energy loss with momentum transfer parallel to the BN layers is dominated by strongly bound, quasi-two-dimensional…

Subterahertz hypersound attenuation in silica glass studied via picosecond acoustics

Simon Ayrinhac, Marie Foret, Arnaud Devos, Benoit Ruffle, Eric Courtens, René Vacher

We report picosecond acoustic measurements in silica-glass films grown by wet thermal oxidation on a (111) silicon substrate. The longitudinal acoustic phonons are observed over the range from 150 to 300 GHz using an infrared pump and a second harmonic blue probe. The transducer is an aluminum thin…

Patterned L10-FePt for polarization of magnetic films

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 the self biasing of magnetic films using micropatterned permanent magnets. Micromagnetic simulations were used as a designing and optimization…

Vortex state in thin films of multicomponent ferroelectrics

Laurent Baudry, Anaïs Sené, Igor A. Luk'Yanchuk, Laurent Lahoche

The distribution of polarization in thin film of multicomponent weak anisotropic ferroelectric under application of an axially symmetric electric field induced by circular electrodes is studied. We demonstrate that above a certain critical field the instability towards abrupt formation of…

Mechanical characterization of aluminium nanofilms

Gregory Guisbiers, Etienne Herth, L. Buchaillot

The mechanical properties (Young’s modulus, hardness, wear resistance) of aluminium nanofilms on silicon substrate are studied. Size effect on these mechanical properties are exhibited. Young’s modulus, hardness and wear resistance increases when the thickness is reduced. Experimental…
