Frequency stable and low phase noise THz synthesis for precision spectroscopy

Léo Djevahirdjian, Loïc Lechevallier, Marie-Aline Martin-Drumel, Olivier Pirali, Guillaume Ducournau, Rédha Kassi, Samir Kassi

We present a robust approach to generate a continuously tunable, low phase noise, Hz linewidth and mHz/s stability THz emission in the 0.1 THz to 1.4 THz range. This is achieved by photomixing two commercial telecom, distributed feedback lasers locked by optical-feedback onto a single highly stable...

Thermodynamics of a single mesoscopic phononic mode

Ilya Golokolenov, Arpit Ranadive, Luca Planat, Martina Esposito, Nicolas Roch, Xin Zhou, Andrew Fefferman, Eddy Collin

In recent decades, the laws of thermodynamics have been pushed down to smaller and smaller scales, within the field of stochastic thermodynamics and state-of-art experiments performed on mesoscopic systems. But these measurements concern mostly thermal properties of electrons and photons. Here we...

A tunable and versatile 28nm FD-SOI crossbar output circuit for low power analog SNN inference with eNVM synapses

Joao Henrique Quintino Palhares, Yann Beilliard, Jury Sandrini, Franck Arnaud, Kevin Garello, Guillaume Prenat, Lorena Anghel, Fabien Alibart, Dominique Drouin, Philippe Galy

In this work we report a study and a co-design methodology of an analog SNN crossbar output circuit designed in a 28nm FD-SOI technology node that comprises a tunable current attenuator and a leak-integrate and fire neurons that would enable the integration of emerging non-volatile memories (eNVMs...

In-Depth Investigation of Manganese Dioxide as Pseudocapacitive Electrode in Lithium- and Sodium-Doped Ionic Liquids

Thibaud Guillemin, Camille Douard, Anthony Impellizzeri, Christopher Ewels, Bernard Humbert, Christophe Lethien, Scott Wilfred Donne, Jean Le Bideau, Thierry Brousse

We investigate the contribution of pseudocapacitance to the overall capacitance of MnO2 electrodes in pure and alkaline-doped ionic liquids via two spectroscopic methods: step potential electrochemical spectroscopy (SPECS) and in situ Raman spectroscopy. For both characterization methods, thin-film...

Ultrafast Modulation of Polarization in Spintronic THz Emitters Enhanced by Field Induced Spin Reorientation Transition

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

We demonstrate an efficient and simple modulation of the polarization in Spin-tronic Terahertz Emitters, by rapid switching of the magnetization using high-frequency magnetic field, enhanced by field induced Spin Reorientation Transition (SRT). The instability of the magnetic layer at the...

High Throughput Characterization Methods at the Wafer Scale for Sputtered Films Used in Micro-Supercapacitors and Li-Ion Micro-Batteries

Pascal Roussel, Aiman Jrondi, Khac Huy Dinh, Bukola Jolayemi, Clément Leviel, Maxime Hallot, Christophe Lethien

The emergence of new miniaturized and autonomous electronic technologies leads to a request of efficient microdevices for energy storage. The development of thin film Li-ion micro-batteries or micro-supercapacitors is an interesting way to power connected sensors, as their manufacturing method is...

Exhaled breath condensate as bioanalyte: from collection considerations to biomarker sensing

Sabine Szunerits, Hannes Dӧrfler, Quentin Pagneux, John Daniel, Shekhar Wadekar, Eloise Woitrain, Dennis Ladage, David Montaigne, Rabah Boukherroub

Since the SARS-CoV-2 pandemic, the potential of exhaled breath (EB) to provide valuable information and insight into the health status of a person has been revisited. Mass spectrometry (MS) has gained increasing attention as a powerful analytical tool for clinical diagnostics of exhaled breath...

Nanomechanical damping via electron-assisted relaxation of two-level systems

Olivier Maillet, Dylan Cattiaux, Xin Zhou, Rasul R. Gazizulin, Olivier Bourgeois, Andrew D. Fefferman, Eddy Collin

We report on measurements of dissipation and frequency noise at millikelvin temperatures of nanomechanical devices covered with aluminum. A clear excess damping is observed after switching the metallic layer from superconducting to the normal state with a magnetic field. Beyond the standard model...
