Physics and Engineering of Nanodevices Group

Group Leader: Sergio Valenzuela

Main Research Lines

  • Development of novel nanodevice structures and nanofabrication methods to investigate the physical properties of materials at the nanoscale and their technological relevance
  • Spin and thermal transport in 2D systems such as topological insulators, graphene and transition metal dichalcogenides
  • Control of the magnetic state of ferro- and antiferromagnetic systems by means of the spin-orbit interaction and, particularly, the spin Hall effect

In 2016 the Physics and Engineering of Nanodevices Group joined the work package dedicated to spintronics of the H2020 Graphene Flagship programme in order to develop spintronic applications with graphene and related 2D materials. The group also continued with its progress on its ERC Starting Grant project to investigate the spin properties of materials with large spin-orbit interaction, in particular topological insulators, achieving thin films with arguably the highest quality available worldwide in a dual-chamber molecular beam epitaxial (MBE) system, and developing spin torque measurements in topological insulator/ferromagnet structures. Work as also been carried out on the national MINECO project, Spintronics in 2-Dimensional Dirac Systems (S2DDS), to investigate the spin Hall effect and the charge and spin transport properties of graphene, including the growth of CVD graphene and the electrical injection and detection of hot carriers. The group has also joined the SpinTronicFactory network to coordinate EU spintronics activities, and became a member of the FWO network (WOG project) on the functional properties of two-dimensional nanostructured materials. Senior group member Dr. Marius V. Costache received a Consejo Superior de Investigaciones Científicas (CSIC) certificate in recognition of his 2015 IUPAP Young Scientist Medal.

Sergio Valenzuela


Prof Valenzuela obtained his PhD in Physics in 2001 at the University of Buenos Aires, Argentina, and went on to be a Postdoctoral Fellow and Research Associate at Harvard University, and a Research Scientist at the Massachusetts Institute of Technology (MIT). Since July 2008, Prof Valenzuela has been an ICREA Research Professor as well as Group Leader of ICN’s, now ICN2’s, Physics and Engineering of Nanoelectronic Devices Group. Since September 2008 he has also served as Associate Professor at the Physics department of the Universitat Autònoma de Barcelona (UAB).
