Design of super directive compact antennas with beam-steering capabilities
Offer N°: SL-DRT-15-0550
Directive compact antennas offer new opportunities for wireless applications in terms of spectral efficiency, reduced environmental impact and use modes. However, the conventional techniques for enhancing the directivity often lead to a significant increase of the antenna size. Consequently, the integration of directional antennas in small wireless devices is limited.
Advanced digital signal processing for color X-ray imaging
Offer N°: SL-DRT-15-0542
Over the last few years there is a growing interest in energy sensitive X-ray detector for color imaging for health, security and non-destructive test applications. Compared to standard radiographic techniques, color imaging provides quantitative information on the density and effective atomic number of the imaged materials.
Study of the surface preparation of III-V and Ge materials with the aim of their integration in the sub 7 nm CMOS transistors
Offer N°: SL-DRT-15-1002
Continued performance scaling of silicon MOS transistors meets immense challenges at sub-10 nm. Therefore, scaling-free technologies are now strongly needed to achieve further improvement of CMOS devices. A number of non-silicon channel materials have been considered for advanced CMOS devices such as SiGe or Ge (PMOS) as well as various III-V materials combinations including InGaAs, GaAs, InAs (NMOS).
Semipolar Nitride materials templates for short wavelength visible emission
Offer N°: SL-DRT-15-0538
III-nitride semiconducting materials are used for the realization of blue diodes at the heart of LED lamps. But when it comes to longer wavelengths (green to red) in the visible domain, these materials encounter difficulties linked to the existence of internal piezoelectric fields that spatially separate electrons and holes in the active region(quantum wells)of the diode, reducing the radiative efficiency.
