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…

Sensors based on AlGaN/GaN HEMT for fast H₂ and O₂ detection and measurement at high temperature

Hassane Ouazzani Chahdi, Omar Helli, Nour Eddine Bourzgui, Leo Breuil, David Danovitch, Paul B Voss, Suresh Sundaram, Vincent Aubry, Yacine Halfaya, Abdallah Ougazzaden, Jean-Paul Salvestrini, Hassan Maher, Ali Soltani

Gas sensors based on AlGaN/GaN transistors are fabricated using platinum gate to detect and to quantify H₂ (1.5-10%) and O₂ (1.5-100%) species at high temperature (500 °C). The metrics ΔI/Δt measured within the 5 first seconds of the transient response…

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…
