PhD in Physics at the Autonomous University of Madrid (UAM) (2001). My PhD focused on the study of friction at the nanoscale in self-assembled monolayers as model lubricant by atomic force microscopy (AFM). One of the most relevant results was the correlation of energy losses to molecular events occurring at specific threshold loads [Phys. Rev. Lett. 82, 2880 (1999)]. In 2001 I acquired a postdoctoral position at the Max-Planck-Institute for Metal Research in Stuttgart (department of Prof. H. Dosch) to extend my experimental skills with synchrotron x-ray diffraction techniques applied to the structural research of organic semiconductor films. In 2002, I became the group leader of the organic group in the same department. The group aimed at advancing the understanding of growth and self-assembly mechanisms of organic semiconducting molecules by employing real-time x-ray diffraction experiments during the growth (from the vapor phase). The final goal was to control the morphology and structure of the organic materials to achieve enhanced the performance in devices. We could generally demonstrate the specific different molecular packing of the organic semiconductors at the dielectric interface and thickness-dependence structural transitions (JACS, 128, 15053 (2006), PRL 103, 136101 (2009)), results of relevance for organic field effect transistors. The research was extended to the investigation of polymers solar cells, in which the active layer is formed by a nanoscale mixture of electron donor and acceptor materials commonly deposited in solution. For that purpose we designed a drying channel that permitted to perform simultaneously x-ray diffraction and optical interferometry. We pioneered the in-situ study of film formation during solvent evaporation to understand the development phase separation and ordering of the donor and acceptor materials to identify the drying parameters that foster the formation of a more optimized nanomorphology for enhanced photovoltaic performance (Chapter “In situ Studies of Morphology Formation in Solution-Processed Polymer–Fullerene Blends” in book Elementary Processes in Organic Photovoltaics, Advances in Polymer Science, Springer).
At the end of 2009, I moved to the Institute of Materials Science of Barcelona (ICMAB-CSIC) as CSIC tenured scientist to open a new research line in the study of functional properties of organic semiconductors at nano- and molecular-scale with Prof. C. Ocal. We have stetted an ultra-high vacuum system of combined scanning tunneling and frequency modulation atomic force microscope (STM/FM-AFM) especially suitable for atomic-scale characterization of the interplay between electronic and geometric structure of organic semiconductors (Group of Physical Chemistry of Surfaces and Interfaces).
