Integrated metrology devices dedicated to transient Harman measurement of silicon nano-meshes

Hafsa Ikzibane, Jon Canosa Diaz, Emmanuel Dubois, J.F. Robillard

In this work, we propose an adaptation of the transient Harman technique to suspendedcrystalline nanomembranes Figure 1 b Additionally, following [ 10 ], a correction factor taking intoaccount radiation, contact resistances and Joule effect is determined. Finally, we present a deviceimplementation…

GeTe thermal characterization with 3-omega and Raman thermometry methods

C. Mercier, A. Patil, J. Canosa Diaz, C. Jerez-Garcia, M. Brouillard, S. Monfray, A. Fleury, B. Reig, Emmanuel Dubois, Pierre-Yves Cresson, J.F. Robillard

Recently, Phase-Change Material technologies are emerging as a potential solution [1-3]. These switches leverage the high electrical conductivity contrast (10 6) between the amorphous and crystalline phases of a chalcogenide material such as GeTe. Their performance could increase the metric fc=1/(…

Fabrication of c-axis LiNbO3 Thin Film for Surface Acoustic Wave Applications

Ngoc Kim Thanh Bui, Nikolay Smagin, Zakariae Oumekloul, Rahma Moalla, William Maudez, Estelle Wagner, Giacomo Benvenuti, Marc Duquennoy, Denis Remiens, Julien Carlier

Lithium niobate (LN) is an important dielectric and ferroelectric materials, which are widely used in acoustics, optic, and optoelectrical devices. In this study, LN thin film was deposited by CBVD method. A SAW delay line and a one-port resonator were fabricated by an e-beam lithography process to…

[Invited] Strategies for Polarization Control in Engineered Spintronic THz Emitters

Nicolas Tiercelin, Geoffrey Lezier, Pierre Kolejak, Jean-Francois Lampin, Kamil Postava, Mathias Vanwolleghem

THz science took off in the 1980 with the discovery by Auston at Bell Labs of the photoconductive switch. Since then, THz science has only slowly developed, and few applications exist despite the enormous potential of the frequency band. One major challenge is the 5-12 THz frequency band, for which…

Low-Power Event-Driven Spectrogram Extractor for Multiple Keyword Spotting: A proof of concept

Soufiane Mourrane, Benoit Larras, Sylvain Clerc, Andreia Cathelin, Antoine Frappé

Keyword spotting (KWS) is one of the major tasks required in online sensing and surveillance devices. This operation requires the processing and analysis of the audio signals that are complex signals with a random distribution of the information in time. In that context, this paper proposes an…

[Invited] High efficiency high robustness Q-band AlN/GaN transistors

F Medjdoub

Power-added-efficiency (PAE) becomes a key parameter in order to support complex waveforms with high peak-to-average ratio and large instantaneous bandwidth required for 5G applications for instance. Overall, a high PAE is mandatory in order to reduce the power dissipation, which is a major issue…
