SPAD for High resolution depthmap
Offer N°: SL-DRT-15-0345
SPAD (Single Photon Avalanche Diode) is the more accurate TOF (Time Of Flight) distance measurement. Some specific issues appear when SPADs are used in matrix to get a depthmap of the scene: sensitivity, compactness, internal speed and integration density are of major concern. Existing SPAD matrix do not allow a large diffusion, although the need is great to improve embedded image treatment efficiency.
Genotoxic effects of graphene
Offer N°: SL-DSM-15-0329
Graphene, monolayer of monocristalline graphite constitued by sp2-hybridized carbon atoms, is considered as one of the most promising nanomaterials, from a technological point of view. Its nanometric dimensions and its unique physico-chemical properties may pose nanosafety concerns. Sustainable development of these nanomaterials thus includes in deep characterization of their toxicological and ecotoxicological properties, which are, up to now, poorly documented.
THz superconducting quantum circuits
Offer N°: SL-DSM-15-0298
Our team fabricates superconducting microwave circuits and measures them at low temperature (10 mK). At these temperatures the quantum character of microwave fields becomes apparent and we can use these circuits to perform quantum optics experiments with microwaves instead of light. We are currently working on different circuits, such as single photon sources and amplifiers with ultra low noise, corresponding to the quantum limit of half a photon.
Modeling of spintronics phenomena in magnetic nanostructures
Offer N°: SL-DSM-15-0340
The ultrafast dynamics of the magnetization in magnetic nanostructures is a key factor for designing new miniaturized electronic devices (e.g. magnetic memories, integrated microwave components, magnetic logic gates,…). To build the active part, concepts such as spin transfer torque or spin-orbit torques are intensively studied experimentally.
