Electric field tuning of magnetization in an antiferroelectric‐based heterostructure: Example of NMG/PLZST/NMG

Liuyang Han, Freddy Ponchel, Nicolas Tiercelin, Denis Remiens, Tuami Lasri, Philippe Pernod, Genshui Wang

A magnetoelectric (ME) heterostructure was fabricated by depositing a Ni-Mn-Ga (NMG) magnetic film on an antiferroelectric (AFE) PLZST-(Pb, La)(Zr, Sn, Ti)O3-ceramic substrate. Significant and reversible electric field-induced relative magnetization changes (∆M/M0) were firstly observed in this…

InAlAs/InGaAs-MSM photodetectors based on optical cavity using metallic mirrors: THz frequency operation, high quantum efficiency and high saturation current

Maximilien Billet, Sara Bretin, Fuanki Bavedila, Vanessa Avramovic, Xavier Wallart, Christophe Coinon, Jean-Francois Lampin, Guillaume Ducournau, Emilien Peytavit

We present a metallic mirror-based resonant cavity-enhanced InAlAs/InGaAs metal-semiconductor-metal (InAlAs/InGaAs-MSM) photodetector driven by a 1550 nm wavelength illumination. The device shows a quantum efficiency higher than 30 %, a cutoff frequency higher than 100 GHz and a saturation current…

Modal and harmonic analyses of a MEMS piezoelectric resonator disc with a complete metallization

Abdessamad Rguiti, Ismail Naciri, Lahoucine Elmaimouni, Youssef Belkassmi, Jean-Etienne Lefebvre, Faniry Emilson Ratolojanahary, A. Rafiki, Salahddine Krit, Ali El Moussati

Orthogonal polynomial approach method has been extended in this paper to the modeling of a piezoelectric disc resonator in case of complete metallization with an excitation electrical source. This method makes use of Legendre polynomials series to express the mechanical displacement components and…

Brillouin light scattering under one-dimensional confinement: symmetry and interference self-canceling

B. Graczykowski, Abdellatif Gueddida, Bahram Djafari-Rouhani, H.-J. Butt, G. Fytas

ABSTRACT We present the spontaneous Brillouin light scattering (BLS) under simultaneous one-dimensional confinement of sound and light and show that the photon-phonon coupling results from nontrivial interplay of the photoelastic and moving-interface effects. We reveal two types of BLS self-…

The design of two-dimensional periodic structures at the nanoscale has renewed attention for band structure engineering. Here, we investigate the nanoperforation of InGaAs quantum wells epitaxially grown on InP substrates using high-resolution e-beam lithography and highly plasma based dry etching…

Caractérisation diélectrique et thermique de films biopolymères pour l’électronique flexible haute fréquence, Dielectric and thermal characterizations of biopolymer films for high frequency flexible electronics

Ghizlane Boussatour

Les matériaux biopolymères sont l’objet d’un engouement très fort pour des applications très variées dans de nombreux domaines d’activités où ils remplacent de plus en plus les polymères pétrosourcés. Compte tenu de leurs propriétés, parmi lesquelles la biocompatibilité, la biodégradabilité, la…, Biopolymer materials attract significant attention in many fields where they tend to replace petrosourced polymers. Thanks to their properties, such as biocompatibility, biodegradability, flexibility and lightness, biopolmyers are also increasingly used in many electronic applications. Nevertheless…
