Characterization of electro-optic coefficients r13 , r23 and r33 in single crystalline BaTiO3 thin films

Yu Cao, Nour Al Meselmene, El Hadj Dogheche, Ping Yang, Parikshit Moitra, Shi Qiang Li, Thirumalai Venkatesan, Aaron Danner

We report experimental characterization of DC electro-optic coefficients r 13 , r 23 and r 33 in thin film single crystalline BaTiO3 on DyScO3 . The epitaxial BaTiO3 thin film is sandwiched between a SrRuO3 bottom electrode and an indium tin oxide (ITO) top electrode. We characterize the DC electro…

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…

Pharmacological inhibitors of β-cell dysfunction and death as therapeutics for diabetes

Stéphane Dalle, Amar Abderrahmani, Eric Renard

More than 500 million adults suffer from diabetes worldwide, and this number is constantly increasing. Diabetes causes 5 million deaths per year and huge healthcare costs per year. β-cell death is the major cause of type 1 diabetes. β-cell secretory dysfunction plays a key role in the development…

High-field 1/f noise in hBN-encapsulated graphene transistors

A. Schmitt, D. Mele, Michael Rosticher, T. Taniguchi, K. Watanabe, C. Maestre, C. Journet, V. Garnier, Gwendal Fève, J. Berroir, Christophe Voisin, B. Plaçais, Emmanuel Baudin

Low-frequency 1/f noise in electronics is a conductance fluctuation, that has been expressed in terms of a mobility ”α-noise” by Hooge and Kleinpenning. Understanding this noise in graphene is a key towards high-performance electronics. Early investigations in diffusive graphene have pointed out a…

Effects of Reaction Parameters on the Geometry and Crystallinity of Hydrothermally Synthesized ZnO Nanorods for Bio-Fouling Applications

Abderrahmane Hamdi, Chin Sing Lim, Mohamed Aymen Ben Achour, Ali Ahmed Alshehri, Mervat Alamri, D. Deresmes, Serena Lay-Ming Teo, Denis Remiens, El Hadj Dogheche

In this present work, we have successfully synthesized vertical aligned ZnO nanorod arrays (ZnO NRs) on conductive stainless-steel substrate. These ZnO NRs were obtained by using a low temperature, low cost, and eco-friendly hydrothermal approach. The effect of the sol-gel deposited ZnO seed layer…

Exploring Machine Learning Privacy/Utility Trade-Off from a Hyperparameters Lens

Ayoub Arous, Amira Guesmi, Muhammad Abdullah Hanif, Ihsen Alouani, Muhammad Shafique

Machine Learning (ML) architectures have been applied to several applications that involve sensitive data, where a guarantee of users' data privacy is required. Differentially Private Stochastic Gradient Descent (DPSGD) is the state-of-the-art method to train privacy-preserving models. However…

Scattering-matrix approach for a quantitative evaluation of the topological protection in valley photonic crystals

Gaëtan Lévêque, Yan Pennec, Pascal Szriftgiser, Alberto Amo, Alejandro Martínez

The realization of photonic crystal waveguides with high topological protection enables robust light propagation against defect-induced scattering. It should allow the design of very compact devices by exploiting guiding through sharp bends with low losses and backreflection. In this work we use…
