Prof. Jordi Arbiol graduated in Physics from the Universitat de Barcelona (UB) in 1997, he went on to obtain his PhD (European Doctorate and PhD Extraordinary Award) in 2001 from this same institution in the field of transmission electron microscopy (TEM) applied to nanostructured materials. He was assistant professor at the UB. From 2009 to 2015 he was ICREA Professor and group leader at the Institut de Ciència de Materials de Barcelona (ICMAB-CSIC), as well as the scientific supervisor of its electron microscopy facilities. He is President of the Spanish Microscopy Society (SME) since 2017 and held the position of vice-president from 2013 to 2017, having been a member of its Executive Board since 2009. In 2018 he was elected as Member of the Executive Board of the International Federation of Societies for Microscopy (IFSM) (2019-2026). Since 2015 he has been ICREA Professor and leader of the Advanced Electron Nanoscopy Group at the Catalan Institute of Nanoscience and Nanotechnology (ICN2), CSIC and BIST. He was awarded the 2014 EU40 Materials Prize by the E-MRS, the 2014 EMS Outstanding Paper Award and was listed in the Top 40 under 40 Power List (2014) by The Analytical Scientist. On February 2020 he has more than 370 peer-reviewed publications and more than 20400 citations (GoS) with h-index: 80 GoS (71 WoS).
Exploring the limits of physical resolution in advanced electron microscopy and understanding the ultimate behavior of materials at the nanoscale and their related properties are the central aims of our research. Our main research lines are:
1) Single atom recognition and localization in embedded quantum and nanostructures. From the atomic resolution data we obtain in the aberration corrected advanced electron microscopes we create 3D atomic models of the nanosystems studied. In this way, we can get full knowledge of the crystal structure, morphology and composition at the atomic scale allowing to understand the growth mechanisms of nanomaterials. We have been able to understand the mechanisms of the polarity-driven growth in free-standing nanostructures like nanowires, nanobelts, and tripods or 2D nanomembranes, or setting paths for the van der waals epitaxy growth mechanisms of semiconductor and oxide nanostructures.
2) Development of methodologies to perform a direct correlation between the structure and elemental composition at the atomic scale and the physical properties at sub-nanometer scale: the new advances in energy resolution in electron microscopy allows us to perform detailed in-situ studies of the photonic, plasmonic and even phononic properties of the nanomaterials, correlated to simulated theoretical models (e.g.: nanosystems for quantum computing, electronics and photonics).
3) Development of in-situ / in-operando experiments in the TEM to understand the physical and chemical phenomena promoting energy mechansims (e.g.: photoelectrochemical) with unprecedented resolution, allowing to correlate the theoretical models with the in-situ TEM and Synchrotron experiments.
