Quality of Service management for distrubuted embedded systems
Offer N°: SL-DRT-15-0659
One of the great challenges of intelligent building and smart home is the interconnection of so called smart objects, whether they are integrated to the building (building management systems, home networks) or specific to the user (brown goods, white goods, portable goods). This interconnection is made difficult by the variety of technologies and the multidisciplinary nature of the objects involved.
Fabrication and testing of multijunction IIIV on Si solar cells
Offer N°: SL-DRT-15-0714
The crystal Silicon photovoltaic industry recently demonstrated record efficiency values over 25%, approaching the Si theoretical limit. Multijunction solar cells based on IIIV materials can overcome this limit: efficiencies over 44% have been reported on 4 junctions under 247suns. Due to the elevated cost of these cells, this technology is dedicated to high concentration.
An intermediate solution consists in combining IIIV and Si materials in order to:
Study of the intra-layer effect, diffusion effect, and shot noise for advanced lithographie
Offer N°: SL-DRT-15-0712
CEA-LETI is leading a program for enabling the Multi-beam lithography technology with low energy. In the frame of this industrial consortium, CEA-LETI is proposing a PhD to deeper understand the pattern roughness for Multi-beam lithography. In the first step the candidates will have to characterize the roughness of the pattern with Scanning Electron Microscope (SEM) and 3D Atomic Force Microscope.
Indirect X-ray photon counting imager for color medical radiology
Offer N°: SL-DRT-15-0614
As part of its activities in medical imaging, Leti has developed over several years several detectors technology, in order to propose new performance in X-ray imaging for different applications like radiology and X-ray CT scanner, gamma-camera, and for non-destructive testing. The first prototypes have shown a great interest in improving the image quality and dose reduction.
