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 »

Control of heat transport at the nanoscale is crucial for many technologies, including thermoelectricity. We have demonstrated by computer simulation of a toy model, that it is possible to design highly ordered systems with thermal conductivities lower than those of completely disordered structures ...

To mimic the copper transport protein Ctr1, responsible for copper entrance into cells, several molecular architectures based on the symmetric scaffold, nitrilotriacetic acid (NTA) functionalized with three amino acids bearing thioether side chains were designed. These thioether derivatives form ... More »

While melanin's role is to protect us when exposed to ultraviolet (UV) radiation from the Sun, the molecules used to make it could produce alterations in the DNA. CEA researchers and their international collaborators have observed this antagonistic effect in melanin production chain for several ... More »

The distribution of the electromagnetic field is an essential input for the design and development of new photonic structures. The classical near-field microscopy tools (SNOM, PSTM ..) allow to obtain this information experimentally. This type of scanning probe microscopy is mainly based on a point ... More »
Researchers from CNRS, CEA, Paris-Sud University and Joseph Fourier University have developed a new process for producing light emitting diodes (LED) flexible. These researchers have produced the first green nanowires-based flexible LED in the world and the first multilayer system combining blue ... More »

Light sources fully integrated into microelectronics technology are the missing stones of silicon photonics. Silicon, as well as germanium, are not well suited for light emission in their natural form, due to the indirect nature of their bandgap. In the case of Ge, this limitation can potentially ... More »

Nanowire transistors in the sub10 nm range are subject to process variability. A main cause is the surface roughness of the nanowire. A single dopant centered in the channel can also modify the room temperature electrical characteristics of the transistor.  Both the surface roughness and a ... More »
Magnetic devices made from the same thin film and subjected to the same electric excitation switch opposite to each other due to their different shape. The magic about the art of paper folding is that from the same sheet of paper one can create so many different objects. Unfortunately, the ... More »

A recent approach for cancer cells destruction was proposed, based on the triggering of cancer cell spontaneous death through the mechanical vibration of anisotropic magnetic nanoparticles attached to the cells membrane at low frequencies (20Hz) and in weak magnetic fields ( a few mT). The ... More »

During writing of Thermally Assisted Switching Magnetic Random Access Memory (TAS-MRAM), the torque due to a voltage pulse may be used to help writing. As part of collaboration between Spintec and Crocus Technology, we brought out that most of the influence of the spin transfer torque is exerted ... More »

Abstract The interfacial structures between magnetic/non-magnetic films play a crucial rule in spintronic devices. In particular, Tunneling magneto-resistance (TMR) is extremely sensitive to the band structure of ferromagnet/insulator interfaces.  In this sense, a number of experimental and ... More »
One solution to meet the new microelectronics and very advanced processes issues is to use Magnetic Tunnel Junctions (MTJ), adding mainly the non-volatility to the integrated circuits. This enables to improve the performance, especially in terms of power consumption and new ... More »
The maximization of Hex/HC ratio (Hex being the exchange bias field and HC the coercive field) and Hex thermal stability are key aspects to improve the performances of Thermally Assisted Magnetic Random Access Memory (TA-MRAM). These properties can be enhanced on a IrMn/Co based exchange biased ... More »
