Atomic-scale and optical investigation of nanostructured Er disilicates in silica
The optical and structural properties of Er-doped Silicon oxide based thin films elaborated by RF magnetron sputtering were investigated as a function of annealing treatment. Atom Probe Tomography and Transmission electron microscopy were used to analyze the position of rare-earth ions as well as the phase separation occurring in the layer in order...
Gas discrimination by simultaneous sound velocity and attenuation measurements using uncoated capacitive micromachined u...
Published in Scientific Reports
Chemically functionalized or coated sensors are by far the most employed solution in gas sensing. However, their poor long term stability represents a concern in applications dealing with hazardous gases. Uncoated sensors are durable but their selectivity is poor or non-existent. In this study, multi-parametric discrimination is used as an alternat...

Efficient Rigorous Coupled-Wave Analysis Simulation of Mueller Matrix Ellipsometry of Three-Dimensional Multilayer Nanos...
Mueller matrix ellipsometry (MME) is a powerful metrology tool for nanomanufacturing. The application of MME necessitates electromagnetic computations for inverse problems of metrology determination in both the conventional optimization process and the recent neutral network approach. In this study, we present an efficient, rigorous coupled-wave an...
Molecular beam epitaxial growth of multilayer 2D-boron nitride on Ni substrates from borazine and plasma-activated nitro...
...Published in Nanotechnology
2D boron nitride (2D-BN) was synthesized by gas-source molecular beam epitaxy on polycrystalline and monocrystalline Ni substrates using gaseous borazine and active nitrogen generated by a remote plasma source. The excess of nitrogen atoms allows to overcome the thickness self-limitation active on Ni when using borazine alone. The nucleation densit...
Silicon nanowires-based biosensors for the electrical detection of Escherichia coli
One of the main challenges in terms of public health concerns the prevention of bacterial contamination using rapid, highly sensitive and specific detection techniques. The development of highly sensitive bacterial sensors for Escherichia coli detection based on networks of silicon nanowires has been carried out in this work. The interest of these ...
Coupling simulation and accelerated degradation model for reliability estimation: Application to a voltage regulator
This paper demonstrates the use of numerical simulation data, depending on the behavior of a low voltage dropout regulator, for reliability performance estimation based on the accelerated degradation test data. The regulator was designed using Cadence Virtuoso software in 180 nm AMS CMOS technology, and simulated to evaluate its output voltage vari...
Experimental Demonstration of Multilevel Resistive Random Access Memory Programming for up to Two Months Stable Neural N...
In recent years, artificial intelligence has reached significant milestones with the development of deep neural networks, but it suffers from a major limitation: its considerable energy consumption. [1] This limitation is primarily due to the energy cost of exchanging information between computation and memory units. [2,3] Memristors, also called r...
A Fokker–Planck-based Monte Carlo method for electronic transport and avalanche simulation in single-photon avalanche di...
...Published in Journal of Physics D: Applied Physics
We present an efficient simulation method for electronic transport and avalanche in single-photon avalanche diodes (SPAD). Carrier transport is simulated in the real space using a particle Monte Carlo approach based on the Fokker–Planck point of view on an advection-diffusion equation, that enables us to reproduce mobility models, including electri...
