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...

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...

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...

Performances of the negative tone resist AZnLOF 2020 for nanotechnology applications

Etienne Herth, Emmanuelle Algre, Pascal Tilmant, Martin François, Christophe Boyaval, Bernard Legrand

We present electron-beam lithography results on an AznLOF2020 UV negative tone resist. This study aims to define electron-beam lithography parameters compatible with microelectromechanical systems/nanoelectromechanical systems fabrication. Usually, one of the properties of the resist material is...

Ta/TiN midgap full-metal single gate fabrication using combined chlorine-based plasma and highly selective chemical metal etching for decananometer CMOS technology

Z.K. Chen, Emmanuel Dubois, F. Ravaux, Francois Danneville

High permittivity dielectric and metal gate are now the most demanded in advanced CMOS technology to overcome conventional polysilicon gate structure drawbacks. However, existing metal gate fabrication approaches are not capable to meet all the demands in terms of material engineering or...

Towards highly scaled AlN/GaN-on-silicon devices for millimeter wave applications

F Medjdoub, Malek Zegaoui, B. Grimbert, Damien Ducatteau, N. Rolland, Paul-Alain Rolland

In this work, the possibility to achieve GaN-on-Si devices for millimeter wave applications operating at high bias is demonstrated. It is shown that highly scaled AlN/GaN-on-Si double heterostructure enables to significantly improve the electron confinement under high electric field as compared to...

Low power sessile droplets actuation via modulated surface acoustic waves

Michael Baudoin, Philippe Brunet, Olivier Bou Matar, Etienne Herth

Low power actuation of sessile droplets is of primary interest for portable or hybrid lab-on-a-chip and harmless manipulation of biofluids. In this paper, we show that the acoustic power required to move or deform droplets via surface acoustic waves can be substantially reduced through the forcing...
