Highlights 2018

Colloidal suspensions of electrically charged nanometric sheets (nanosheets), like graphene oxide or clays, which are widely used in industry, can form liquid-crystalline phases.

Liquid state NMR is used to investigate surface state of CuInS2 nanocrystals (NCs). 1H and 13C NMR studies of NCs dispersed in organic solvent allowed characterizing and quantifying the ligands at the NC surface, while diffusional NMR enabled studying ligand binding dynamics.
In May 2018, Thierry Douki (INAC / SYMMES) received the American Photobiology Society Award in Tampa, Florida during the congress of the American Society of Photobiology.
Three-dimensional mesoporous inverse opal TiO2 nanostructures were synthesized and efficiently transferred into the photoelectrodes of dye sensitized solar cells.

Telomeres, regions of the DNA (highly repetitive and therefore a priori non-coding) located on the ends of chromosomes, play an important role in cell division, carcinogenesis and aging.

V. Calvo and N. Pauc at INAC/PHELIQS/ SiNaPS 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.

We report ballistic transport in a one-dimensional (1D) channel made of germanium quantum well and reveal an anisotropic variation of the hole g-factor as a function of the orientation of the magnetic field.
The coexistence of ferromagnetism and superconductivity is a rare and surprising phenomenon. Three resent studies carried out in INAC help understand the pairing mechanism is these systems.

Research on silicon-based spin qubits is currently extensively pursued looking for a viable pathway towards large-scale integration.

Individual stretching of graphene layers in a van der Waals stack drastically modifies the electronic properties of the whole structure. This result opens new possibilities for the strain-engineering of 2D materials.

We have recently reported that pure spin conductors could behave as nonlinear component in the high power regime, hereby opening up considerably the realm of functions realizable with magnetic materials. An additional feature is that these are continuously tunable by an external magnetic field.
Contact : Gilles Gaudin
We report on the wave-vector independent detection of short-waved spin waves with wavelengths down to 150 nm by the inverse spin Hall effect in spin-wave waveguides made from CMOS-compatible sputtered Ta/CoFeB/MgO.
This study discuss the shift observed in spintronics from the current-perpendicular-to-plane geometry towards lateral geometries, illustrating the new opportunities offered by this configuration.
Magnetic tunnel junctions are the basic elements of a new class of magnetic memory called MRAM (Magnetic Random Access Memory). These are about to enter in volume production at major microelectronics foundries (Samsung, TSMC, Global Foundries…).
