Current researches

Research engineer in the hybrid spintronic team since 2020, I’m in charge of the hybrid cluster growth facility. This all UHV-integrated system gather a sputtering chamber, a metal evaporation chamber and a chamber dedicated to the evaporation of molecule. The facility is particularly well adapted for the growth of multilayers of metals, simple oxides and molecules typically for molecular spintronic applications. I’m also in charge of the molecular beam epitaxy facility dedicated to the growth of metals and simple oxides systems.

My research interest is now focusing on the oxocarbon acids family (CnH2On). These simple molecules are exhibiting ferroelectric (n=5; n=6) and anti-ferroelectric (n=4) properties that could be advantageously integrated in hybrid multilayer devices.
