Nanoscale Studies at the Early Stage of Water-Induced Degradation of CH 3 NH 3 PbI 3 Perovskite Films Used for Photovoltaic Applications

Jaume Llacer, David Moerman, Olivier Douheŕet, Xavier Noirfalise, Claudio Quarti, Roberto Lazzaroni, Didier Theron, Philippe Leclere

Understanding the surface properties of hybrid perovskite materials is a key aspect to improve not only the interface properties in photovoltaic cells but also the stability against moisture degradation. In this work, we study the local electronic properties of two series of CH 3 NH 3 PbI 3…

Substrate engineering of inductors on SOI for improvement of Q-factor and application in LNA

Arun Bhaskar, Justine Philippe, Vanessa Avramovic, Flavie Braud, J.F. Robillard, Cédric Durand, Daniel Gloria, Christophe Gaquière, Emmanuel Dubois

High Q-factor inductors are critical in designing high performance RF/microwave circuits on SOI technology. Substrate losses is a key limiting factor when designing inductors with high Q-factors. In this context, we report a substrate engineering method that enables improvement of quality factors…

High Q THz photonic crystal cavity on a low loss suspended Silicon platform

Elias Akiki, Marc Faucher, Mathias Vanwolleghem, Mattias Verstuyft, Bart Kuyken, Benjamin Walter, Jean-Francois Lampin, Guillaume Ducournau

In this work, we present an ultra-high Q cavity at Terahertz (THz) frequencies. The designed cavity is built on a low loss suspended silicon (Si) waveguide. The substrate removal under the waveguide and the use of optimized deep reactive ion etching processing is the main reason for observing very…

Cell selective manipulation with single beam acoustical tweezers.

Michael Baudoin, Jean-Louis Thomas, Roudy Al Sahely, Jean-Claude Gerbedoen, Zhixiong Gong, Aude Sivery, Olivier Bou Matar, Nikolay Smagin, Peter Favreau, Alexis Vlandas

Acoustical tweezers open major prospects in microbiology for cells and microorganisms contact- less manipulation, organization and mechanical properties testing since they are biocompatible, label-free and can exert forces several orders of magnitude larger than their optical counterpart at…

Electrical activity at the AlN/Si Interface: identifying the main origin of propagation losses in GaN-on-Si devices at microwave frequencies, Activité électrique de l'interface AlN/Si: identification de l'origine principale des pertes de propagation en hyperfréquences dans les composants GaN sur Silicium

Micka Bah, Damien Valente, Marie Lesecq, N. Defrance, Maxime Garcia Barros, Jean-Claude de Jaeger, Eric Frayssinet, Rémi Comyn, Thi Huong Ngo, Daniel Alquier, Yvon Cordier

AlN nucleation layers are the basement of GaN-on-Si structures grown for light-emitting diodes, high frequency telecommunication and power switching systems. In this context, our work aims to understand the origin of propagation losses in GaN-on-Si High Electron Mobility Transistors at microwaves…

Thermal resistance of an interfacial molecular layer by first-principles molecular dynamics

Thuy-Quynh Duong, Carlo Massobrio, Guido Ori, Mauro Boero, Évelyne Martin

The approach-to-equilibrium molecular dynamics (AEMD) methodology is applied in combination with first-principles molecular dynamics (FPMD) to investigate the thermal transfer between two silicon blocks connected by a molecular layer. Our configuration consists of alkanes molecules strongly coupled…
