Guided-wave electro-optic characterization of BaTiO3 thin films using the prism coupling technique

Floriane Leroy, Anthony Rousseau, Sandrine Payan, El Hadj Dogheche, David Jenkins, Didier Decoster, Mario Maglione

Ferroelectric BaTiO3 (BTO) thin films are grown by RF sputtering onto an indium tin oxide bottom electrode on a MgO single-crystal substrate. We have studied here the optical properties by the prism coupling technique. We report the ordinary and extraordinary refractive indices of the films, the...

22 Gbps wireless communication system at 0.4 THz

Guillaume Ducournau, P. Szriftgiser, Fabio Pavanello, Philipp Latzel, Alexandre Beck, Tahsin Akalin, Emilien Peytavit, Mohammed Zaknoune, Denis Bacquet, Jean-Francois Lampin

By combining a lJTC-PD as a THz emitter and a 400 G Hz Schottky-based heterodyne detection, we realized an indoor THz link working up to 22 Gbps at 400 GHz carrier frequency with ultra-low THz power. The eye diagram at receiver is clearly opened are the system is working with only 1 mu W received...

Exploring electronic structure of one-atom thick polycrystalline graphene films : a nano angle resolved photoemission study

J. Avila, I. Razado, S. Lorcy, R. Fleurier, E. Pichonat, D. Vignaud, X. Wallart, M.C. Asensio

The ability to produce large, continuous and defect free films of graphene is presently a major challenge for multiple applications. Even though the scalability of graphene films is closely associated to a manifest polycrystalline character, only a few numbers of experiments have explored so far...

Characteristics of the surface microstructures in thick InGaN layers on GaN

Y. El Gmili, G. Orsal, K. Pantzas, A. Ahaitouf, T. Moudakir, S. Gautier, G. Patriarche, David Troadec, Jean-Paul Salvestrini, A. Ougazzaden

This paper focuses on a comparative study of optical, morphological, microstructural and microcompositional properties of typical InGaN samples which exhibit V-defects but also two additional surface defects features, referred to as inclusion#1 (Ic1) and inclusion#2 (Ic2). HR-XRD, AFM, SEM, STEM...

Focused ion beam Ga3+ for the realization of piezoelectric PZT nano structures

Denis Remiens

Piezoelectric nano-structures (islands of dimensions in the lateral size range 50-500 nm) have been fabricated by Focused Ga3+ Ion Beam (FIB) etching on PbZr0.54Ti0.46O3 thin films obtained by magnetron sputtering. The degradation induced by the etching process is investigated through the evolution...
