Research

Experimental study of the electric properties of low dimensional and nano systems, focusing on superconducting and ferromagneting materials. The systems under study include ultrathin films, nanowires, quantum dots, tunnel junctions and nanoparticles. The various research projects deal with the effect of   geometry, size and disorder on the electric and magnetic properties of these systems.
