Epitaxy of quaternary InGaAlN layers for high performace transitors

Offer N°: SL-DRT-16-0659

Start date: 1 Oct 2016

CEA is dedicated to working on Atomic and Alternative Energy, to advance clean technologies using science and technology. As part of these developments, CEA-LETI is developing high power transistors and low energy LEDs with several major companies. For high power transistors, the goal is to have components working at high voltage, and passing a current of up to 100A.


Ion-beam-induced migration of HgCdTe dopants and application to p-n junction formation

Offer N°: SL-DRT-16-0649

Start date: 1 Sep 2016

HgCdTe crystal is a semiconductor material with the unusual feature to be highly ion-beam sensitive. This thesis proposal covers the specificity of this material to exhibit a migration of dopants under ion-beam irradiation. This specificity, demonstrated for some dopants of HgCdTe, is of major technological interest by letting foreseen the possibility to finely tune p-n junction.


3D holographic microscopy: study of a new interferometric microscope for the real-time 3D imaging of complex biological structures

Offer N°: SL-DRT-16-0139

Start date: 1 Oct 2016

Our laboratory develops unconventional microscopy techniques like lensless and interferometric microscopy. The subject of this thesis is to extend a previous work dedicated to microbiology to more complex structures like cells network and skin tissues. During this thesis, the student will further develop the instrument and the processing method to provide true 3D images without specimen labelling.


Impact study and simulation of the a stress field on optical devices in a 3D interposer for advanced silicon photonics.

Offer N°: SL-DRT-16-0430

Start date: 1 Jan 2016

In the context of short and medium distance transfers of very large amount of numerical data, silicon photonics is an emerging area that provides proven solutions to a major societal challenge. It allows extremely dense data exchanges at low energy cost, perfectly suited to large Datacenters needs.
