Light harvesting by planar photonic crystals in solar cells: the case of amorphous silicon
Guillaume Gomard,Guillaume Gomard,Guillaume Gomard,Meng Xianqin,Meng Xianqin,Meng Xianqin,Emmanuel Drouard,Emmanuel Drouard,Khalil El Hajjam,Khalil El Hajjam,Emmanuel Gerelli,Emmanuel Gerelli,Romain Peretti,Romain Peretti,Alain Fave,Alain Fave,Regis Orobtchouk,Regis Orobtchouk,Mustapha Lemiti,Mustapha Lemiti,Christian Seassal,Christian Seassal +21 more
TL;DR: In this article, the light management in silicon thin film solar cells, using photonic crystals (PhC) structures, is discussed by means of optical simulations performed on realistic thin-film solar cell stacks.
Journal ArticleDOI
Area selective deposition of TiO2 by intercalation of plasma etching cycles in PEALD process: A bottom up approach for the simplification of 3D integration scheme
Rémi Vallat,R. Gassilloud,Olivier Salicio,Khalil El Hajjam,Gabriel Molas,Bernard Pelissier,Christophe Vallée,Christophe Vallée +7 more
TL;DR: In this article, a modified plasma enhanced atomic layer deposition (PEALD) sequence was developed in a modified PEALD-TiO2 sequence for bottom-up approach, where the metal oxide selectivity was obtained on TiN versus Si-based surfaces by adding one etching/passivation plasma step of fluorine every n cycles in a PEALD TiO2 process.

Sub-pJ consumption and short latency time in RRAM arrays for high endurance applications
Gilbert Sassine,Cecile Nail,L Tillie,Diego Alfaro Robayo,Alexandre Levisse,Carlo Cagli,Khalil El Hajjam,Jean-Francois Nodin,Elisa Vianello,Mathieu Bernard,Gabriel Molas,Etienne Nowak +11 more
TL;DR: In this paper, programming operations are optimized for low energy consumption and short latency time applications in RRAM kb arrays and innovative circuit with on the fly switching detection is proposed, allowing to reduce programming consumption down to single pJ operation in large memory arrays.
Journal ArticleDOI
Tunnel Junction Engineering for Optimized Metallic Single-Electron Transistor
Khalil El Hajjam,Mohamed Amine Bounouar,Nicolas Baboux,Serge Ecoffey,Marc Guilmain,Etienne Puyoo,Laurent Francis,Abdelkader Souifi,Dominique Drouin,Francis Calmon +9 more
TL;DR: In this article, an engineered single-electron transistor (SET) based on multidielectric stacking was proposed to insure high-ON current, low-OFF current, and low capacitance.
Proceedings ArticleDOI
Study of the Energy Consumption Optimization on RRAM Memory Array for SCM Applications
Carlo Cagli,Gabriel Molas,Michel Harrand,S. Bernasconi,C. Charpin,Khalil El Hajjam,Jean Francois Nodin,Gilles Reimbold +7 more
TL;DR: This paper focuses on the programming operation optimization of a HfO2-based Resistive RAM (RRAM) memory array for low power consumption application, and shows how the resistance window depends on the write/erase energy.
