DC performance of high-quantum-efficiency 1.3µm GaNAsSb/GaAs waveguide photodetector

Z. Xu, N. Saadsaoud, Malek Zegaoui, Wan Khai Loke, Kianhuan Tan, S. Wicaksono, Soon Fatt Yoon, Christiane Legrand, Didier Decoster, Jean Chazelas

We present the dc performance of a high-quantum-efficiency GaNAsSb/GaAs p-i-n waveguide photodetector. GaNAsSb with N and Sb contents of 3.3% and 8%, respectively, is sandwiched by AlGaAs/GaAs cladding layers. Two types of device epilayer structures, i.e., with and without AlGaAs cladding layer,…

Rigorous extraction tunability of Si-integrated Ba0.3Sr0.7TiO3 thin film up to 60 GHz

Freddy Ponchel, Jean-François Legier, Caroline Soyer, Denis Remiens, Jean Midy, Tuami Lasri, Guillaume Guéguan

400-nm-thick Ba0.3Sr0.7TiO3 thin films are deposited on high resistivity silicon by in situ radio frequency magnetron sputtering. Coplanar waveguides with 1µm slot width are designed, with accurate knowledge frequency losses behavior, to determine ferroelectric thin-films properties up to 60 GHz.…

Interface depolarization field as common denominator of fatigue and size effect in Pb(Zr0.54Ti0.46)O3 ferroelectric thin film capacitors

Rachid Bouregba, N. Sama, Caroline Soyer, Gilles Poullain, Denis Remiens

Dielectric, hysteresis and fatigue measurements are performed on Pb(Zr0.54Ti0.46)O3 (PZT) thin film capacitors with different thicknesses and different electrode configurations, using platinum and LaNiO3 conducting oxide. The data are compared with those collected in a previous work devoted to…

Two-dimensional Legendre polynomial modeling of composite bulk acoustic wave resonators

A. Raherison, Jean-Etienne Lefebvre, F.E. Ratolojanahary, L. Elmaimouni, Tadeusz Gryba

A bidimensional analysis of 6 mm hexagonal resonators is described using a double orthonormal basis set for the expansion of field quantities. The analysis takes into account the electrical voltage source and by means of a unique formalism along with a single calculation restitutes all the types of…

Negative refraction of zero order flexural Lamb waves through a two-dimensional phononic crystal

Juliette Pierre, Olga Boyko-Kazymyrenko, Laurent Belliard, Jerome O. Vasseur, Bernard Bonello

We investigate experimentally the refraction of antisymmetric Lamb waves at frequencies in the second band of a two-dimensional phononic crystal. The heterostructure is made of a square lattice of air inclusions in a silicon plate. Our experimental scheme is based on the selective generation of…

Control of III-V nanowire crystal structure by growth parameter tuning [Invited]

Kimberly A. Dick, Philippe Caroff, Jessica Bolinsson, Maria E. Messing, Jonas Johansson, Knut Deppert, L.R. Wallenberg, Lars Samuelson

In this work we investigate the variation of the crystal structure of gold-seeded III–V nanowires with growth parameters, in order to gain a cohesive understanding of these effects. We investigate six III–V materials: GaAs, InAs, GaP, InP, GaSb and InSb, over a variation of growth conditions. All…
