Electronic Properties of Single Prussian Blue Analog Nanocrystals Determined by Conductive-AFM

Hugo Therssen, Laure Catala, Sandra Mazérat, Talal Mallah, Dominique Vuillaume, Thierry Melin, Stéphane Lenfant

We report a study of the electron transport (ET) properties at the nanoscale (conductive-AFM noted C-AFM thereafter) of individual Prussian Blue Analog (PBA) cubic nanocrystals (NCs) of CsCo(III)Fe(II), with size between 15 and 50 nm deposited on HOPG. We demonstrate that these PBA NCs feature an...

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...

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...

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...

Capacity Improvement of 3D-OCDMA-PON Hybrid System Next Generation Using Weight Zero Cross Correlation Code

Abdelhamid Cherifi, Tarik Mohammed Chikouche, Abdullah Karar, Julien Moussa H. Barakat, Omar Arbouche, Iyad Dayoub

This paper proposes a novel code for optical code division multiple access (OCDMA) systems, called the three-dimensional (3D) spectral/temporal/spatial single weight zero cross-correlation (3D-SWZCC) code. The proposed code could potentially be used in the next generation of passive optical...

[Review] Host miRNAs as biomarkers of SARS-CoV-2 infection: a critical review

Kato Pollet, Nathalie Garnier, Sabine Szunerits, Annemieke Madder, Didier Hober, Ilka Engelmann

MicroRNAs (miRNAs), small non-coding RNAs that regulate gene expression, have received increasing attention as potential biomarkers of different diseases, including viral infections. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the disease it is causing, coronavirus...
