Silicon Based Suspended Thermometry Device Fabrication for Phonon Ballistic and Coherent Regimes Study

J. Canosa Diaz, H. Ikzibane, B. Brisuda, C. Polanco Garcia, L. Saminadayar, N. Mingo, Olivier Bourgeois, Emmanuel Dubois, J.F. Robillard

This works addresses the current experimental gap in thermal transport regimes and phonon transport at low temperatures and small scales. We have fabricated a (SOI based) suspended thermal sensor platform functional from room-T down to 20 mK. The device will be used for the study phonon transport…

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…

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…

Interlaboratory investigation of on-wafer S parameter measurements from 110 GHz to 1.1 THz

Xiaobang Shang, Nick Ridler, Uwe Arz, Gia Ngoc Phung, Isabelle Roch-Jeune, Guillaume Ducournau, Kamel Haddadi, Thomas Flisgen, Ralf Doerner, Djamel Allal, Divya Jayasankar, Jan Stake, Robin Schmidt, Gavin Fisher, Faisal Mubarak

This paper presents an interlaboratory comparison of on-wafer S-parameter measurements of coplanar waveguide (CPW) devices in the frequency range of 110 GHz to 1.1 THz. The comparison was conducted using bespoke calibration standards and verification devices fabricated from high resistivity Silicon…

Progress in process development of La0.7Sr0.3MnO3 thin films for uncooled THz bolometers

Thomas Quinten, Yoann Lechaux, Victor Pierron, Chantal Gunther, Laurence Méchin, Jean-Francois Lampin, Marc Faucher, Benjamin Walter, Bruno Guillet

We present preliminary results of uncooled THz bolometers based on La 0.7 Sr 0.3 MnO 3 thin films on SrTiO3 buffered high resistivity silicon substrates. Fabrication improvements enable to obtain low contact resistance and the impedance measurements show that it is possible to minimize the…
