Thermal response and correlation between mobility and kink effect in GaN HEMTs

Mohammad A. Alim, S. Afrin, A. A. Rezazadeh, Christophe Gaquière

This work notices the relation among the kink effect and the mobility in AlGaN/GaN HEMT and its response to temperature. The kink phenomenon found in transistor behaviour are carefully characterized at persuade point which is straightaway linked to the shallow traps positioned underneath the…

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…

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…

Interaction of cellulose and nitrodopamine coated superparamagnetic iron oxide nanoparticles with alpha-lactalbumin

Fakhrossadat Mohammadi, Marzieh Moeeni, Chengnan Li, Rabah Boukherroub, Sabine Szunerits

In recent years, numerous studies have focused on the understanding of the interactions between proteins and nanoparticles (NPs). In this work, we focus on the interaction of bovine α-lactalbumin (BLA) with differently coated magnetic nanoparticles (MP): as formed MP, MPs stabilized with dopamine (…

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…
