Searching for THz Gunn oscillations in GaN planar nanodiodes

Ana Iniguez-De-La-Torre, Ignacio Íñiguez-De-La-Torre, Javier Mateos, Tomás González, Paul Sangare, Marc Faucher, Bertrand Grimbert, Virginie Brandli, Guillaume Ducournau, Christophe Gaquière

A detailed study of GaN-based planar asymmetric nanodiodes, promising devices for the fabrication of room temperature THz Gunn oscillators, is reported. By using Monte Carlo simulations, an analysis of the static I-V curves and the time-domain evolution of the current obtained when varying some…

Vitro study of the impact of sédimentsartificiellement contaminated with anthracene: Effects on indigenous bacteria and the marine nematode [Étude in vitro de l'impact de sediments artificiellement contaminés par l'anthracène: Effets sur les bactéries indigènes et les nématodes libres marins]

O.B. Said, Hela Louati, A. Soltani, E. Mahmoudi, Cristiana Cravo-Laureau, O. Pringault, Robert Duran, P. Aissa

This study evaluates the in vitro impact of three bioremediation techniques: biostimulation, bioaugmentation, and a combination of biostimulation and bioaugmentation on microflora and nematofauna after an artificial contamination of lagoon sediments by anthracene. This sediment contamination tends…

Ultrasound tests in a stirred vessel to evaluate the reconstitution ability of dairy powders

B. Richard, Malika Toubal, J.F. Le Page, Georges Nassar, Edouard Radziszewski, Bertrand Nongaillard, P. Debreyne, P. Schuck, Romain Jeantet, Guillaume Delaplace

This study demonstrated the feasibility of applying an ultrasound test to evaluate the ability of a powder to interact with a solvent and thus to predict the reconstitution behaviour of powders. The ultrasound attenuation was monitored and a corresponding relaxation time was calculated. Analysis of…

Non-radiative complete surface acoustic wave bandgap for finite-depth holey phononic crystal in lithium niobate

Didit Yudistira, Yan Pennec, Bahram Djafari-Rouhani, Samuel Dupont, Vincent Laude

We demonstrate the existence of non-radiative complete surface acoustic wave(SAW)bandgaps for two-dimensional piezoelectric phononic crystals of holes. Holes of finite depth in a semi-infinite LiNbO3 substrate are specifically considered. SAWbandgaps are determined from the band structure…

CBRAM devices as binary synapses for low-power stochastic neuromorphic systems: auditory (cochlea) and visual (retina) cognitive processing applications

M. Suri, O. Bichler, D. Querlioz, G. Palma, E. Vianello, D. Vuillaume, C. Gamrat, B. de Salvo

In this work, we demonstrate an original methodology to use Conductive-Bridge RAM (CBRAM) devices as binary synapses in low-power stochastic neuromorphic systems. A new circuit architecture, programming strategy and probabilistic STDP learning rule are proposed. We show, for the first time, how the…
