Dilute Magnetic Semiconductors for Spintronics. 

In this research line, we study the electronic structure and optical properties of semiconductors doped with magnetic impurities (DMS, Diluted Magnetic Semiconductors) using advanced electron microscopy techniques, scanning tunneling microscopy, paramagnetic electron resonance, and X-ray photoelectron spectroscopy. 

Our goal is to determine the origin of the ferromagnetism of DMS and to fabricate spintronic devices type spin-photodiodes and spin-valves.
