Elastic Metasurfaces for Deep and Robust Subwavelength Focusing and Imaging

Yabin Jin, Wan Wang, Abdelkrim Khelif, Bahram Djafari-Rouhani

Metasurfaces are planar metamaterials with a flat surface and a subwavelength thickness that are able to shape arbitrary wave fronts such as focusing or imaging. There is a broad interest in the literature about subwavelength focusing and imaging based on bulk metamaterials while the utilization of...

New barrier layer design for the fabrication of gallium nitride-metal-insulator-semiconductor-high electron mobility transistor normally-off transistor

Flavien Cozette, Bilal Hassan, Christophe Rodriguez, Eric Frayssinet, Rémi Comyn, François Lecourt, Nicolas Defrance, Nathalie Labat, François Boone, Ali Soltani, Abdelatif Jaouad, Yvon Cordier, Hassan Maher

This paper reports on the fabrication of an enhancement-mode AlGaN/GaN metal-insulator-semiconductor-high electron mobility transistor with a new barrier epi-layer design based on double Al 0.2 Ga 0.8 N barrier layers separated by a thin GaN layer. Normally-off transistors are achieved with good...

20 Gbit/s 306 GHz link enabled by Yagi-Uda antenna

Guillaume Ducournau, Fabio Pavanello, Aritrio Bandyopadhyay, Cybelle Belem-Gonçalves, Frédéric Gianesello, Cyril Luxey, Emilien Peytavit, Jean-Francois Lampin, Malek Zegaoui, Mohammed Zaknoune

We report on the use of a Yagi-Uda antenna on polymer substrate used in a 306 GHz-20 Gbit/s real-time data link for indoor applications. The Yagi-Uda antenna is described and the validation of the THz link is obtained in amplitude modulation mode and using QAM-16 signals (32 Gbit/s).

Piezoresistance in defect-engineered silicon

Heng Li, Abel Thayil, Chris Lew, Marcel Filoche, Brett Johnson, Jeff Mccallum, S. Arscott, Alistair C. H. Rowe

The steady-state, space-charge-limited piezoresistance (PZR) of defect-engineered, silicon-on-insulator device layers containing silicon divacancy defects changes sign as a function of applied bias. Above a punch-through voltage (Vt) corresponding to the onset of a space-charge-limited hole current...
