Evidence of optically induced degradation in gallium nitride optoelectronic devices

Carlo de Santi, Alessandro Caria, Nicola Renso, Ezgi Dogmus, Malek Zegaoui, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni, Matteo Meneghini

We provide experimental evidence that gallium-nitride-based optoelectronic devices can be affected by a photon-driven degradation mechanism unrelated to catastrophic optical damage. Any role of current in such degradation is excluded by stress tests under laser irradiation in the open-circuit…

Chapter 2 - Phonon monomode circuits

El Houssaine El Boudouti, Abdellatif Akjouj, L. Dobrzynski, Bahram Djafari-Rouhani, Housni Al-Wahsh, Gaëtan Lévêque, Yan Pennec

In this chapter, we discuss the vibrational properties of phononic circuits that can be described in the framework of discrete or continuous models. In the case of discrete media, we use the phonon discrete model within the Green’s function method described in Chapter 1 and give the surface…

Analytical model for the energy harvesting of a spherical sensor from ambient vibrations

Daher Diab, Fabrice Lefebvre, Georges Nassar, Nikolay Smagin, Adnan Naja, Fawaz El Omar

In this work an analytical model for the energy harvesting of an acoustic spherical sensor has been developed in the context to make it autonomous. Our spherical sensor is composed of two half-spheres of Plexiglas and a piezoelectric ring of PZ26 that can be used as exciter or sensor. For the…

Graphene FETs Based on High Resolution Nanoribbons for HF Low Power Applications

David Mele, Sarah Mehdhbi, Dalal Fadil, Wei Wei, Abdelkarim Ouerghi, Sylvie Lepilliet, Henri Happy, Emiliano Pallecchi

In this paper we present high frequency field effect transistors based on graphene nanoribbons arrays (GNRFETs). The nanoribbons serve as a channel for the transistors and are fabricated with a process based on e-beam lithography and dry etching of high mobility hydrogen intercalated epitaxial…

Highly Sensitive Surface Acoustic Wave Magnetic Field Sensor Using Multilayered TbCo2/FeCo Thin Film

Aurelien Mazzamurro, Abdelkrim Talbi, Yannick Dusch, Omar Elmazria, Philippe Pernod, Olivier Bou Matar, Nicolas Tiercelin

Over the last decades, the use of Surface Acoustic Waves (SAW) has emerged as a promising technology in many applications such as filters, signal processing but also sensors. We report the fabrication and the characterization of a SAW delay line magnetic field sensor using uniaxial multi-layered…
