Simulation, design, crystal growth, fabrication and testing of semiconductor devices for
optoelectronics and power conversion, including the following achievements:
▫ First demonstration of the direct high-temperature growth of gallium nitride (GaN) on Si(111)
substrates by metalorganic vapor phase epitaxy (MOVPE), enabling the realization of verticallyconducting
GaN/Si hetero-structures for power electronics and LEDs
▫ First demonstration of the direct high-temperature growth of GaN on ScAlMgO4 by MOVPE
▫ Improvement of the light emission from multiple quantum wells grown on InGaN on ScAlMgO4
▫ First demonstration of high-voltage fully-vertical p-InGaN/GaN Schottky diodes with ultra-low onstate
resistance, exploiting the piezoelectric field in the InGaN layer
▫ Realization of high-voltage quasi-vertical GaN Schottky diodes with nickel oxide terminations

De Janvier 2016 à Décembre 2018
During my fellowship at CERN, I have worked on the development of a radiation resistant, LED-based, lighting system for particle accelerator tunnels, including the following activities:
• Design, simulation, prototyping and testing of radiation resistant power supplies for LEDs
• Organization of irradiation campaigns at CERN irradiation test facilities (IRRAD) and external laboratories (Ionisos, France) for optical materials, electronic and optoelectronic components
• Development of ad hoc measuring instruments for irradiated samples
• Detailed study and analysis of radiation effects on:
- Electronic components for power supply units, including GaN transistors, Si bridge diodes, SiC Junction Barrier Schottky diodes
- High-Brightness High-Power white GaN LEDs
- Glass and plastic materials for secondary optics
• Support in writing tender documentation for the procurement of radiation hard luminaires implementing the developed radiation tolerant power supply for LEDs.
My research efforts led to working prototypes of LED luminaires able to withstand the radiation levels expected in >5 years of operation in CERN tunnels (annual dose >1 kGy, annual 1 MeV neutron equivalent fluence >5x1e12 n/cm2).
In parallel, I worked as Deputy Project Manager for the refurbishment of the low voltage electrical infrastructure of the Proton Synchrotron Booster (PSB) accelerator and of the Proton Synchrotron (PS), and Project manager for the electrical systems of the future extension of SX5 building, with tasks including:
- Production of a detailed inventory of existing distribution infrastructure
- Development of proposals for upgraded and new distribution systems, including: detailed engineering of new solutions for the low voltage infrastructure, preparation of documents for quotation, and the supervision of low voltage installation works
- Planning and follow-up of activities on site
- Commission equipment on site, prepare and archive test reports
