Ultraviolet‐Durable Flexible Nonfullerene Organic Solar Cells Realized by a Hybrid Nanostructured Transparent Electrode

Tao Xu, Chunliu Gong, Shuanglong Wang, Hong Lian, Weixia Lan, Gaëtan Lévêque, B. Grandidier, Jerome Plain, Renaud Bachelot, Bin Wei, Furong Zhu

A significant enhancement in ultraviolet (UV)-durable indium tin oxide (ITO)-free flexible nonfullerene organic solar cells (OSCs) is demonstrated using a hybrid nanostructured flexible transparent electrode (FTE), comprising a mixture of 0D silver nanoparticles, 1D Ag nanowires, and 2D exfoliated…

The limits of edge bead planarization and surface levelling in spin-coated liquid films

S. Arscott

A model is presented here to predict fluid reflow in a viscous liquid film having time-dependent physical properties. The model is applied to the practical example of the reflow planarization (surface levelling) of 'edge bead' features resulting from the spin coating process. During the…

Power Domain NOMA Without SIC in Downlink CSS-Based LoRa Networks

Angesom Ataklity Tesfay, Eric Pierre Simon, Ido Nevat, Laurent Clavier

Low Power Wide Area Network, such as LoRa is one of the main building blocks of the Internet of Things. One of the main issues is to scale up the number of devices and one strong limitation comes from the downlink communication. In fact, the access point is constrained by the duty cycle, therefore…

LoS theoretical and experimental MIMO study from 1-40 GHz in indoor environments

Juan Pascual-Garcia, Maria-Teresa Martinez-Ingles, Davy Gaillot, Leandro Juan-Llacer, Jose-Maria Molina-Garcia-Pardo

In this work, line-of-sight multiple-input multiple-output (MIMO) measurements in the frequency range from 1 GHz to 40 GHz are presented for an indoor environment in the scope of new 5G bands. For the sake of comparison, the measured radio channels are reproduced with great accuracy using ray…

Non-reciprocal Behavior of One-dimensional Piezoelectric Structures with Space-time Modulated Electrical Boundary Conditions

Charles Croënne, Sarah Tessier, Jerome O. Vasseur, Olivier Bou Matar, Anne-Christine Hladky, Bertrand Dubus

Propagation of longitudinal acoustic waves in a one-dimensional piezoelectric structure with space-time modulated electrical boundary conditions is investigated. An analytical model allowing the calculation of eigenmodes for spatially continuous shifts of electrical boundary conditions is compared…

Low-frequency noise parameter extraction method for single-layer graphene FETs

Nikolaos Mavredakis, Wei Wei, Emiliano Pallecchi, Dominique Vignaud, Henri Happy, Ramon Garcia Cortadella, Nathan Schaefer, Andrea Bonaccini Calia, Jose Antonio Garrido, David Jimenez

In this article, a detailed parameter extraction methodology is proposed for low-frequency noise (LFN) in single-layer (SL) graphene transistors (GFETs) based on a recently established compact LFN model. The drain current and LFN of two short channel back-gated GFETs (L = 300 and 100 nm) were…

Aerodynamic wall pressure measurement using a high temperature gradient Pirani micro-sensor

Cécile Ghouila-Houri, Munique Kazar Mendes, Thomas Arnoult, Romain Viard, Quentin Gallas, Eric Garnier, Alain Merlen, Abdelkrim Talbi, Philippe Pernod

This paper presents and discusses the first demonstration of aerodynamic wall pressure measurement using a thermal Pirani effect based micro-sensor. The thermal micro-sensor is designed as a suspended micro-hot-wire separated from the substrate by a nanoscale gap, and mechanically supported by…
