Fabrication of silicon nitride membrane nanoelectromechanical resonator

Hao Xu, Srisaran Venkatachalam, Christophe Boyaval, Pascal Tilmant, Francois Vaurette, Yves Deblock, Didier Theron, Xin Zhou

In this work, we present details of the nanofabrication process for achieving a silicon nitride nanoelectromechanical resonator, consisting of a membrane covered with a thin aluminium layer capacitively coupled to a suspended top gate. Critical nanofabrication steps have been discussed, including...

Metal-based folded-thermopile for 2.5D micro-thermoelectric generators

Ibrahim Bel-Hadj, Zahia Bougrioua, Katir Ziouche

We report on the simulation and fabrication of 2.5D micro-thermoelectric generators (µTEGs) with a thermopile topology periodically folded and distributed on a multi-membrane template, capable of harvesting lost heat directly into useful electrical energy. The originality of the folded thermopile...

Topological vortex mode for flexural waves in pillared plates

Zhihui Wen, Julio Andrés Iglesias Martínez, Yabin Jin, Yan Li, Bahram Djafari-Rouhani, Daniel Torrent, Jean-Louis Raynaud, Abdelkrim Khelif

Localized topological modes with high robustness to various perturbations are receiving increasing attention. Recently, zero-order topological vortex modes have been designed in phononic structures, in analogy with zero-energy fermionic states modulated by Jackiw-Rossi binding mechanism. Such...

THz topological Waveguides in 600 GHz frequency Region

Abdu Subahan Mohamed, Edouard Lebouvier, Gaëtan Lévêque, Yan Pennec, Marc Faucher, Alberto Amo, Pascal Szriftgiser, Guillaume Ducournau

We experimentally demonstrate a silicon-based valley photonic crystal (VPC) waveguide for the 590-620 GHz frequency region. We specifically conduct measurements on the transmission and group delay for normal silicon waveguides and Valley photonic crystal waveguides and state that topological valley...

One-channel time reversal focusing of ultra-high frequency acoustic waves on a MEMS

Hatem Dahmani, Nikolay Smagin, P. Campistron, J. Carlier, Malika Toubal, Bertrand Nongaillard

This Letter reports on a work performed to fabricate and characterize a silicon micro-machined cavity dedicated to micro-resolution Ultra-High Frequency imaging in microfluidics and microbiological applications using one-channel time reversal. Time reversal provides the means to spatially and...

Robust Al0.23Ga0.77N channel HFETs on bulk AlN for high voltage power electronics

J. Mehta, Idriss Abid, Reda Elwaradi, Yvon Cordier, F Medjdoub

AlxGa1-xN heterojunction FETs (HFETs) have been an eye catcher for high voltage power electronics with its potential to outperform the predecessors by virtue of high critical breakdown field of the material, which can be tuned by varying Al mole-fraction. In this work, we demonstrate Al0.23Ga0.77N...

Highly stable fluorine-free slippery liquid infused surfaces

Anne-Sophie Vaillard, Manon Saget, Flavie Braud, Marc Lippert, Laurent Keirsbulck, Maude Jimenez, Yannick Coffinier, Vincent Thomy

A promising Slippery Liquid Infused Surface (SLIS) has been developed, that is both easy-to-produce and environmentally friendly. Using a double replication method, a 200 µm-thick texturized cross-linked PDMS film was obtained, leading to a grid of micrometric hills and deep wells. A comparison...
