Ferroelectric (116) SrBi2Nb2O9 thin films epitaxially grown by pulsed laser deposition on epitaxial (110) Pt/(110) SrTiO3 electrode

Jean-René Duclere, Maryline Guilloux-Viry, A. Perrin, Eric Cattan, Caroline Soyer, Denis Remiens

Epitaxial SrBi2Nb2O9 thin films have been grown by pulsed-laser deposition on (110)Pt bottom electrode epitaxially grown on (110) SrTiO3 by dc sputtering. X-ray φ-scans and electron channeling patterns reveal the epitaxial growth of the (116) SrBi2Nb2O9/(110)Pt bilayers. The hysteresis loop,…

Unsupervised characterization of digital modulations

David Boulinguez, Christelle Garnier, Yves Delignon, Laurent Clavier

With the rising number of modulation types used in multi-user communication systems, we need to find efficient methods to discriminate them. Indeed, modulation recognition has become important in wireless communications for both civilian and military applications. Traditionally, to classify…

High linearity performance of gallium nitride HEMT devices on silicon substrate at 4 GHz

Nicolas Vellas, Christophe Gaquière, Yannick Guhel, Matthieu Werquin, Frédéric Bue-Erkmen, Sylvain Laurent Delage, B. Boudart, Fabrice Semond, Jean-Claude de Jaeger

In this letter, we demonstrate that, for high linearity application, GaN devices benefit from their high drain-source bias voltages. An improvement up to 20 dB in intermodulation ratio can be observed at high power levels compared to usual GaAs PHEMT devices. This study demonstrates that the high…
