Optical transmitter III-V epitaxial growth on Silicon
Offer N°: SL-DRT-16-0677
For over 25 years, the heart of telecom networks has become one of the fields of application of III-V components (InP_like and AsGa_like). This field is based on the IR wave transmission in optical fibers fed by III-V materials laser sources. For a dozen years a new technological route has been developed, Silicon-Photonics, which lowers manufacturing costs by increasing integration density (integrating 3D Wafer Level Packaging).
Development architected materials to improve healing
Offer N°: SL-DRT-16-0658
The department of technologies for biology and health (DTBS) CEA Grenoble (France) designs and develops medical devices for improving the diagnosis and treatment of patients. Presently, chronic wounds represent 500 000 burns of which 10 000 require hospitalization, 300 000 bedsores, 600 000 leg ulcers and 120 000 diabetic foot ulcers of which 10 000 require amputation. Considering the aging population and decreasing hospital stay, these trends are bound to increase.
DC/DC converter based on piezoelectric material and adiabatic power transfer
Offer N°: SL-DRT-16-0747
The aim of this thesis is to design high-efficiency power converters based on resonating piezoelectric transducers. A large part of the work is to develop the electrical cycle able to energetically maintain the piezoelectric resonator in resonance and ensure zero-voltage switching, for electrical energy transfer from the source to the piezoelectric resonator or from the piezoelectric resonator to the output, in order to minimize the losses.
Epitaxy of quaternary InGaAlN layers for high performace transitors
Offer N°: SL-DRT-16-0659
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.
