In the context of the study of the interplay between magnetism and superconductivity, a phase transition has been evidenced as a function of magnetic field between two phases having identical magnetic symmetry. Since this effect cannot be magnetically driven, it implies a modification of the nature ... More »

The properties of hard X-ray to excite light emission can be combined simultaneously with X-ray fluorescence techniques to study nanoscale devices as demonstrated for multiple quantum well (MQW) InGaN/GaN core/shell wires integrated in blue LED emitters. This study allowed us to understand the ... More »

It has been shown in recent years that mechanical stress can be used to tune the electronic and optical properties of semiconductor quantum dots. For instance, this approach has been implemented to adjust finely the emission wavelength of quantum dot single photon sources. In view of real ... More »

Electronic structure calculations based on the Density Functional Theory are widely applied to materials and molecules. Nevertheless, there are limited to systems with few hundred of atoms because the operation scaling is cubic versus the number of atoms. Thanks to the locality properties of ... More »

Damien Massy, SP2M/NRS, received the best presentation award at the E-MRS Fall meeting 2015 for his paper called “Alternative Smart-Cut integration on silicon”. The paper was about Damien’s PhD work, on Acoustic Emission from Crack Propagation in the Smart Cut™ Technology.
Legend: Q-constant energy scans (solid symbols), at two Bragg positions shown in the inset, fitted by a series of Gaussian functions (solid lines). This figure emphasizes one series of transverse modes when the scattering vector Q is parallel to the direction of the ordered antiferromagnetic ... More »

In oleaginous seeds, the energy reserves are mainly triacylglycerols that are liquid lipids contained inside micrometric vesicles, called oil bodies (OB). Seeds are of first importance for human and animal feeds, for biofuels sources and their economic weight is far from being negligible. Therefore ... More »
Self-organized nanoclusters in a thin film elaborated by sol-gel, this is possible ! The nanocluster organization is closely related to the pore arrangement in the annealed films. This discovery of scientists from INAC/SP2M, LITEN and University Grenoble Alpes still widens the applications ... More »
Yannick MARTIN, who recently finished his PhD at SP2M/LEMMA has been awarded the NanoART monthly prize in September 2014.   NanoART is a Nano Imagery contest sponsored by nRai®, and organized in Grenoble by the Nanoscience Foundation.   Website for ... More »
CEA researchers associated with the CNRS and the University of Grenoble-Alpes have succeeded for the first time to observe the 3D ultra-thin layer of the polymer ion-exchange polymer contained in the electrodes of a fuel cell, which hosts electrochemical reactions that produce electricity. ...

Mesoporous alumina (Al2O3) presents itself as a technologically important material due to its high surface area and catalytic properties. However, the characterization of this material remains elusive to various techniques. Using a hyperpolarization technique called dynamic nuclear polarization ... 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 »
