The meeting brought together some forty European and Japanese experts in charge of coordination and components for future tokamak JT-60SA which ... More »
The use of strained silicon is a fundamental of modern nano-electronics, allowing to increase the mobility of charge carriers up to 150%. Researchers from INAC (in collaboration with LETI and ESRF) measured the deformation of individual silicon lines at the nanoscale. With the miniaturization of ... More »
We have modeled for the first time devices developed at LETI and STMicroelectronics with quantum methods. These simulations have provided important information on the physics of these devices. The industry of microelectronics has constantly sought to reduce the characteristic dimensions of ... More »

The eighth edition of the Alpine Conference on Solid-State NMR took place in Chamonix in September 2013.  With over two hundred participants from twenty different countries, the conference is traditionally marked by the awarding of a prize in memory of R. Regitze Vol. The price ... More »
The cell wall of bacteria is composed of several biopolymers building a shell around the cell, which allows recognition and adhesion to hosts, as well as regulation of other important cellular functions. A better understanding of the complex cell wall structure and interactions may help ... More »
Lithium ion batteries (LIB) are considered as prime candidates for electric vehicles. Among them, batteries with silicon nanoparticles (SiNPs) based negative electrode are very promising, thanks to their important energy storage capacity, ten times higher than the current ones. But their low ... More »

Performances of the membrane-electrode assembly in polymer electrolyte fuel cells strongly depend on the features of the catalyst layer. This is a complex interface region which forms during the fabrication process, when the ionomer mixes with carbon supported platinum nanoparticles, ... More »
MRI is a non-invasive diagnostic tool providing high-resolution anatomical images consisting of 3D maps of the relaxation rates of the hydrogen nuclei in the body. However, its potential for molecular or functional imaging is limited by the low sensitivity of these rates to natural variation ... More »

Electron pumps are devices delivering a quantized current when driven at a frequency f: I=Nef, where N is an integer and e the electron charge. Electron pumps capable of delivering a current higher than 100 pA (corresponding to f >600MHz) with sufficient accuracy are likely to become the direct ... More »

The software Kwant is ​​available to the scientific community at http://kwant-project.org. This new platform aims beyond the traditional goal of making simulations fast, i.e. efficient in terms of computer time.  Kwant allows researchers to study new quantum-physical ... More »
Extreme conditions of high pressure, associated with low temperatures and high magnetic field are the corner stone for the exploration of  the phase diagrams of strongly correlated electron systems, and therefore for the discovery of new states of matter and of the interplay between the ... More »
Researchers from SP2M demonstrate a novel optical antenna which funnels very efficiently the emission of a semiconductor quantum dot into a Gaussian optical beam.

Spintronics applications use ferromagnetic(F)/antiferromagnetic(AF) exchange bias (EB) interactions to set the reference direction required for the spin of conduction electrons. They therefore may involve layers intermixing originating from F/AF interfaces. As a consequence of intermixing, ... More »

Usually, magnetic tunnel junctions consist of electrodes made of an alloy of cobalt, iron and boron (CoFeB) and a tunnel barrier in magnesium oxide (MgO). To bring perpendicular anisotropy to such structures, multilayers of cobalt and platinum (Co/Pt) may be used. However, it is necessary to ... More »
In May, at the "International Memory Workshop" organized by the IEEE in California, Spintec and Crocus Technology presented the first demonstration of magnetic memory cells capable of performing a logic function. This patented concept opens the possibility to perform functions related to ... More »
