Optimization of the inverted perovskite CH3NH3PbI3 planar heterojunction for solar cells applications

M. Kemouche, A. Aissat, S. Nacer, S. Dupont, Jean-Pierre Vilcot

The purpose of our paper is to simulate and optimize the electro-optical characteristics of a reversed Perovskite planar solar cell. Firstly, the synthesis of the CH3NH3PbI3 was exposed. Then, the absorption, reflection and transmission phenomena were studied. The effects of the thicknesses of…

Determination of the solid surface energy of tellurium dioxide

G. Guisbiers, E. Badradeen, S. Arscott

Tellurium dioxide is an ultra-wide bandgap semiconductor material playing a key role in optoelectronics. However, some of its physico-chemical properties such as the solid surface energy are still unknown. Indeed, the values available in the literature are scarce and contradictory. In this letter,…

Emerging GaN Technologies for Next-Generation Millimeter-Wave Applications

Farid Medjdoub, Keisuke Shinohara, Fabian Thome, Jeong-Sun Moon, Eduardo Chumbes, Matthew Guidry, Umesh Mishra, Enrico Zanoni, Matteo Meneghini, Gaudenzio Meneghesso, James Pomeroy, Terirama Thingujam, Martin Kuball

Advanced millimeter-wave (mm-wave) transceiver systems, including future mm-wave 5G and 6G mobile networks, are of great interest to support high-data-rate communications (e.g., 10 Gb/s or higher) and backhaul communications with >50 Gb/s. Since the E band and beyond can also support…

Control of the preferentially orientated growth of Sr2TiSi2O8 crystals in a SrO – TiO2 – SiO2 – Al2O3 – K2O parent glass

Oussama Zwein, Marie-Sophie Renoirt, Maurice Gonon, Nicolas Preux, Sandra Abdelouhab, Rıdvan Yildiz, Marc Duquennoy

A polar glass-ceramic containing Sr-fresnoite Sr2TiSi2O8 (STS) as single crystalline phase was developed through the controlled crystallization of a parent glass composition containing SrO, TiO2, SiO2, K2O, and Al2O3. The objective of this work is to obtain a piezoelectric substrate exhibiting a…

LLR estimation using machine learning

Latifa Mostari, Alban Goupil, Abdelmalik Taleb-Ahmed

Many decoders of error-correcting codes use the Log-Likelihood Ratio (LLR) as an input, which involves the probability density function (pdf) of the noise. In impulsive noise, the pdf of the noise is not accessible in closed form and is only available through very complex numerical computation.…

Etude de la forme de la cavite sur les parametres des accelerometres thermiques

Valentin Toulmé, Soukaina Ben Salk, Marc Faucher, Philippe Combette, Alain Giani

<div>RESUME<p>Les accéléromètres thermiques à convection (ATC) sont développés mesures à haute intensité, ce que ne peuvent pas faire les accéléromètres classiques du fait de la présence de masse sismique dans leur conception. Le sujet présenté ici porte paramètres des ATC (plage de…

Spin valve as THz emitter providing amplitude modulation

A. Buryakov, E. Mishina, E. Lebedeva, P. Yu. Avdeev, N. Tiercelin, S. Ovcharenko, A. Gorbatova, A. Klimov, A. Sigov, V. Preobrazhensky

We present a novel spin-valve THz emitter composed of FeCo/TbCo2/FeCo tri-layers separated by a copper spacer, designed to provide amplitude modulation of THz radiation. The distinct coercivities of the magnetic layers enable magnetic field control of the THz emission, with the final amplitude…

Cell senescence and the DNA single-strand break damage repair pathway

Parvathy A Sarma, Corinne Abbadie, Yvan de Launoit, Fabrizio Cleri

Cellular senescence is a response to endogenous and exogenous stresses, including telomere dysfunction, oncogene activation and persistent DNA damage. In particular, radiation damage induces oxidative base damage and bond breaking in the DNA double-helix structure, which are treated by dedicated…
