  Nanodevices, transport and spintronics

 

Spintronic: The goal of this research line is to identify active transport channels in nanometer-size devices grown on electrical gates, their spin polarization and their electrical properties as a function of the magnetic state. We collaborate with the area of FIB/SEM, in the LMA, to produce nanowires, dots, rings, flakes, etc, using the existing nanodeposition facilities, to contact them with three terminals and inspect the transport characteristics with the local probe devices. We expect to identify spin channels and accumulation at interfaces, to observe thermo magnetic transport properties and, in general to map in space magnetic and electrical response to external actions in three terminal devices.
