Dr. Fabián Calleja Mitjá
Fabián Calleja obtained his BSc (2001) and MSc (2002) in Physics from the Universidad Autónoma de Madrid. He then joined the group of Prof. Rodolfo Miranda in the Surfaces Laboratory of the Universidad Autónoma de Madrid, where he obtained his PhD in 2007. Then he joined the group of Prof. Harald Brune in the Laboratory of Nanostructures at Surfaces of the Federal Politechnical School of Lausanne (EPFL) as a post-doctoral researcher. In January 2011 he joined IMDEA Nanoscience, where he is currently hired as a researcher. At present FC works in two independent UHV STM systems: The LT-STM laboratory (standard 4K bath cryostat) and the JT-STM laboratory (Joule-Thompson 1K cryostat and 3T superconducting magnet).
• Our research career is devoted to the study of the electronic and magnetic properties of nanometric systems often based on graphene, ranging from isolated atoms or molecules to clusters of arbitrary size or networks. The main goal is to achieve a deep understanding of the interaction between the different nanostructures and graphene, and the corresponding modification of graphene’s intrinsic properties, an important milestone in the potential development of graphene-based spintronic devices. Current research lines are based on metal-supported graphene systems, and can be split in two main groups: The adsorption of organic molecules on metal-supported graphene (Nature Physics 9, 368 - 374, 2013) and the intercalation of heavy metal atoms between graphene and the underlying metallic substrate (Nature Physics 11, 43 - 47, 2015).
