Effect of phonon confinement on the dispersion relation and heat capacity in nanoscale Si membranes

J. Cuffe, E. Chávez, A. Shchepetov, P.O. Chapuis, E.H. El Boudouti, F. Alzina, Yan Pennec, Bahram Djafari-Rouhani, M. Prunnila, J. Ahopelto, C.M. Sotomayor Torres

The effect of confinement on the acoustic phonon dispersion relation and heat capacity in free-standing silicon membranes is investigated, with thickness values down ∼ 8 nm. The discrete phonon branches are observed by angle-resolved inelastic light scattering spectroscopy. The fundamental flexural…

Physical aspects of low power synapses based on phase change memory devices

M. Suri, O. Bichler, D. Querlioz, B. Traore, O. Cueto, L. Perniola, V. Sousa, D. Vuillaume, C. Gamrat, B. de Salvo

In this work, we demonstrate how phase change memory (PCM) devices can be used to emulate biologically inspired synaptic functions in particular, potentiation and depression, important for implementing neuromorphic hardware. PCM devices with different chalcogenide materials are fabricated and…

Switching properties of nano-scale multi-axial ferroelectrics : geometry and interface effects

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

We consider the nonuniform polarization switching in the electroded nanoscale cubic ferroelectric, having the nano-size cylindric shape. Assuming the weak anisotropy, that can be realized e.g. in Lead Zirconate Titanate close to morphotropic point, we show that vortex-like polarization texture can…

Band gap tunability of magneto-elastic phononic crystal

Olivier Bou Matar, J.F. Robillard, Jerome O. Vasseur, Anne-Christine Hladky, P.A. Deymier, Philippe Pernod, Vladimir Preobrazhensky

The possibility of control and tuning of the band structures of phononic crystals offered by the introduction of an active magnetoelastic material and the application of an external magnetic field is studied. Two means to obtain large elastic properties variations in magnetoelastic material are…

Kinetics of N2(B3Πg) and N2(C3Πu) states in N2-Ar discharges sustained by a RF helical coupling device

Corinne Foissac, Jaroslav Krištof, Adriana Annusova, Pavel Veis, Philippe Supiot

A kinetic model is discussed for the two main emitting species (N2(B), N2(C)) of a N2-Ar plasma excited at 27 MHz by a helical cavity with operating pressure of 200 Pa. The present paper consistently illustrates, for miscellaneous Ar fractions and different positions, the great influence of the…
