Atomic scale investigation of silicon nanowires and nanoclusters

Manuel Roussel, W.H. Chen, Etienne Talbot, Rodrigue Lardé, E. Cadel, F. Gourbilleau, B. Grandidier, D. Stievenard, Philippe Pareige

In this study, we have performed nanoscale characterization of Si-clusters and Si-nanowires with a laser-assisted tomographic atom probe. Intrinsic and p-type silicon nanowires (SiNWs) are elaborated by chemical vapor deposition method using gold as catalyst, silane as silicon precursor, and…

Statistical analysis of multipath clustering in an indoor office environment

Emmeric Tanghe, Wout Joseph, M. Lienard, Abdelmottaleb Nasr, Paul Christian Stefanut, Luc Martens, Pierre Degauque

A parametric directional-based MIMO channel model is presented which takes multipath clustering into account. The directional propagation path parameters include azimuth of arrival (AoA), azimuth of departure (AoD), delay, and power. MIMO measurements are carried out in an indoor office environment…

Phase change memory as synapse for ultra-dense neuromorphic systems: application to complex visual pattern extraction

Manan Suri, Olivier Bichler, Damien Querlioz, Olga Cueto, Luca Perniola, Véronique Sousa, Dominique Vuillaume, Christian Gamrat, Barbara Desalvo

We demonstrate a unique energy efficient methodology to use Phase Change Memory (PCM) as synapse in ultra-dense large scale neuromorphic systems. PCM devices with different chalcogenide materials were characterized to demonstrate synaptic behavior. Multi-physical simulations were used to interpret…

Energy-band engineering for improved charge retention in fully self-aligned double floating-gate single-electron memories

Xiaohui Tang, Christophe Krzeminski, Aurelien Lecavelier Des Etangs-Levallois, Zhenkun Chen, Emmanuel Dubois, Erich Kasper, Alim Karmous, Nicolas Reckinger, Denis Flandre, Laurent A. Francis, Jean-Pierre Collinge, Jean-Pierre Raskin

We present a new fully self-aligned single-electron memory with a single pair of nano floating gates, made of different materials (Si and Ge). The energy barrier that prevents stored charge leakage is induced not only by quantum effects but also by the conduction-band offset that arises between Ge…
