Introduction

 Spintronics Theory Group

Research Interests

My currect works is about the theoretical modeling of metal/organic semi-conductors interfaces employing ab-initio methods. I am modeling different ferromagnetic-organic interface, implying aromatic molecules and metal-macrocyclic planar aromatic molecules and interfaces such as irom, cobalt, tungsten and MgO surfaces. I am focusing on the role of the organic molecules in the local control of the spin polarization inversion close to the Fermi level. The main goal, will be understand the different parameters responsible of the efficiency increase of future molecular spintronic devices, by selecting the candidate of organic semi-conductors.

I am also
involved in the diluted magnetic semi-conductors project, where we are using the numerical tools for modeling ZnO based DMO in different structures : bulk, thin-films and nanostructures.
