Émilie Sakat






CNRS Research Fellow




Tel : +



Emilie Sakat is a CNRS researcher since 2016. She received her PhD thesis in 2013 on the « Spectral filtering in the midinfrared based on subwavelength gratings ». She obtained the Airbus Foundation’s award for her PhD. Then, she did a postdoc at Politecnico di Milano, where she was involved in a project aiming at using heavily-doped semiconductors for a plasmonic platform. One goal was to retrieve the optical properties of epitaxially grown n-Ge layers at IR frequency, beyond the assumption of the Drude model. She was also involved in a project with the Molecular Foundry in Berkeley dedicated to the fabrication and the characterization of an AFM tip apex functionalized with epitaxially grown n-Ge. Finally, she did a postdoc at LCF on thermal emission before entering at CNRS.

Key words : Plasmonics, Metasurfaces, Heavily-doped semiconductors, Infrared, Near-Field microscopy
