Devices and circuits for HF applications based on 2D materials

Simon Skrzypczak, Di Zhou, Wei Wei, Dalal Fadil, Dominique Vignaud, Emiliano Pallecchi, Henri Happy

Graphene and related 2D materials have been extensively studied in recent years. As a result, numerous components have been developed for a wide range of applications in high frequency electronics and telecommunications. These include graphene field effect transistors (GFET) which can be used to…

Acoustic noise levels and field distribution in 7 T MRI scanners

Louena Shtrepi, Vinicius Poggetto, Clement Durochat, Marc Dubois, David Bendahan, Fabio Nistri, Marco Miniaci, Nicola Maria Pugno, Federico Bosia

Acoustic noise production during Magnetic Resonance Imaging is an important source of patient discomfort and leads to verbal communication problems, difficulties in sedation, and hearing impairment. To address these issues, in this paper we present a systematic characterization of the acoustic…

Experimental evidence of nonreciprocal propagation in space-time modulated piezoelectric phononic crystals

S. Tessier Brothelande, C. Croënne, F. Allein, Jerome O. Vasseur, M. Amberg, F. Giraud, Bertrand Dubus

A nonreciprocal system composed of a one-dimensional piezoelectric phononic crystal whose periodic electrical conditions are modulated in time is presented. One-way longitudinal wave propagation is studied experimentally and compared to finite element temporal simulations. The modulation is…

Refractive Index Modification in Thin Film Barium Titanate-on-Insulator and Dry Etch Free Fabrication of Waveguide Devices

Yu Cao, Hong-Lin Lin, Haidong Liang, Andrew Bettiol, El Hadj Dogheche, Aaron Danner

We present refractive index modification methods in thin-film barium titanate-on-insulator with a resultant index change up to 0.17, and propose dry etch free device fabrication methods for optical waveguide devices.

Process optimization of Fully Vertical GaN-on-Silicon PIN diodes

Idriss Abid, Youssef Hamdaoui, Sondre Michler, Katir Ziouche, F Medjdoub

Lateral GaN-on-silicon power transistors are now qualified up to 650 V voltage operation [1]. On the other hand, the development of cost-effective GaN-based vertical devices grown on large diameter silicon substrate combines the advantages of potentially higher voltage operation with avalanche…
