Piezoelectric suspended microchannel resonators
The objective of this PhD thesis is the development of a microfluidic platform for the real-time measurements of the mechanical properties of biological analytes at the single entity level.The systems developed for these purposes consist of piezoelectrical ...
EPFL2022A formula for the admittance of laterally excited bulk wave resonators (XBARs)
Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Victor Plessky
The recently invented laterally excited bulk wave resonators (XBARs) demonstrate outstanding parameters suitable for the design of low loss filters for the fifth generation of mobile phones. The operation of XBARs can be interpreted as an excitation of ant ...
WILEY2021Effects of impurities and local behavior characterization using active thermography on solid oxide electrolysis cells
Ambitious policies are needed from every country to drastically curtail the anthropogenic emission of greenhouse gases responsible for the on-going modification of the earth's climate. A quick transition towards a society fully based on renewable materials ...
EPFL2021Spin-dependent charge transfer at chiral electrodes probed by magnetic resonance
Jean-Philippe Ansermet, Christophe Roussel, Felix Blumenschein, Mika Antero Tamski
Chirality-induced spin selectivity is evidenced by exciting the spin resonance of radicals in an electrochemical cell where the working electrode is covered with a chiral self-assembled monolayer. Because the electron transfer to and from the paramagnetic ...
ROYAL SOC CHEMISTRY2020Fabrication of clamped-clamped beam resonators with embedded fluidic nanochannel
Philippe Renaud, Luis Guillermo Villanueva Torrijo, Annalisa De Pastina, Damien Maillard, Stefano Silvio Giovanni Varricchio, Carlo Ricciardi, Davide Scaiola, Stefano Stassi
Suspended nanochannel resonators (SNRs) are promising devices able to characterize mass down to the attogram scale, thus being able to detect nanoparticles or biomolecules. In this paper, we present a flexible fabrication process for SNRs based on a sacrif ...
ELSEVIER2020Antiferromagnetic resonance in TmFeO3 at high temperatures
Jean-Philippe Ansermet, Arnaud Magrez, Haiming Yu, Marcin Bialek
Temperature dependence of the antiferromagnetic resonance spectrum in a thulium orthoferrite (TmFeO3) poly-crystalline sample was studied by transmission spectroscopy in the frequency range of 0.1–0.75 THz and temperature range of 300–670 K, up to its Néel ...
20205 GHz laterally-excited bulk-wave resonators (XBARs) based on thin platelets of lithium niobate
Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Victor Plessky
In a free-standing 400-nm-thick platelet of crystalline ZY-LiNbO3, narrow electrodes (500 nm) placed periodically with a pitch of a few microns can eXcite standing shear-wave bulk acoustic resonances (XBARs), by utilising lateral electric fields oriented p ...
2019Active Electroacoustic Resonators and their Applications to Non-Hermitian Acoustics
We will discuss our recent experimental progress on developing active acoustic resonators that provide in- dependently tunable acoustic properties, namely the possibility to control at will their resonance frequency, absorption losses, and radiative losses ...
2019Second Harmonic Generation Dynamics in Plasmonic Nanoparticles
Olivier Martin, Jérémy Butet, Gabriel David Bernasconi
Due to its symmetry properties, second-harmonic generation in plasmonic nanostructures enables the observation of even-parity modes that couple weakly to the far field. Consequentially, those modes radiate less and thus have a longer lifetime. Using a full ...
SPIE-INT SOC OPTICAL ENGINEERING2018Excitation and time resolved spectroscopy of SAW harmonics up to GHz regime in photolithographed GaAs devices
Pasquale Scarlino, Marco Scigliuzzo
In this work, we demonstrate the excitation of surface acoustic waves (SAW) harmonics up to GHz regime in photolitographed devices fabricated on gallium arsenide (GaAs) by acting on the IDT metallization ratio among the finger width and pitch. Specifically ...
