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…

Study of enhanced biosensors based on 2-D sandwiched plasmon photonic crystals

Jin-Ying Zhang, He Huang, Wei-Jiang Xu, Julien Carlier, X.M. Ji, Bertrand Nongaillard, J. Zhou, Y.P. Huang

A novel sandwich structure of photonic crystal with periodic square array of hexagon holes was fabricated. The infrared optical properties in reflectance of the devices were tested. A sharp peak of surface plasmon resonance was observed at the incident angles of 30°. By the comparison of the…

Fabrication and characterization of half-Kerfed LiNbO3-based high-frequency (>100MHz) ultrasonic array transducers

Jin-Ying Zhang, Wei-Jiang Xu, Julien Carlier, X.M. Ji, Bertrand Nongaillard, S. Queste, J. Zhou, Y.P. Huang

The effect of kerf depth is investigated on the performances of array transducers. A finite element tool, COMSOL, is employed to simulate the properties of acoustic field and to calculate the electrical properties of the arrays, including crosstalk effect and electrical impedance. Furthermore,…

Squeezing radiation from quantum cascade lasers with leaky waves

Miguel Beruete, Tahsin Akalin, Miguel Navarro-Cia, Guillaume Ducournau, Jean-Francois Lampin, Mario Sorolla

Several flat antennas consisting of a central slot surrounded by a metallic periodic structure are proposed to enhance the radiation of quantum cascade laser terahertz sources. A simulation study of the optimal profile for high gain and radiation efficiency is done. Prototypes are being fabricated

A silicon nanowire ion-sensitive field-effect-transistor with elementary charge sensitivity

N. Clement, K. Nishiguchi, Jean-François Dufrêche, David Guérin, A. Fujiwara, D. Vuillaume

We investigate the mechanisms responsible for the low-frequency noise in liquid-gated nanoscale silicon nanowire field-effect transistors (SiNW-FETs) and show that the charge-noise level is lower than elementary charge. Our measurements also show that ionic strength of the surrounding electrolyte…
