Sergio Fernández Garrido graduated in Physics with honors at Universidad Autónoma de Madrid (UAM) in 2003. In 2004, he was awarded with a fellowship for the training of university personnel (FPU) to carry out his PhD at Instituto de Sistemas Optoelectrónicos y Microtecnología (ISOM), a “Major Scientific Facility” from Universidad Politécnica de Madrid (UPM). His PhD was on the analysis of the synthesis and properties of group-III nitride compound semiconductors, the material system that revolutionized solid-state lighting and high-power/high-frequency electronics. During his PhD, he was visiting scientist in 2 foreign research centers: the Solid-State Lighting and Display Center at University of California Santa Barbara (USA) (4 months in 2006), and the High-Pressure Research Center of the Polish Academy of Sciences (Poland) (3 months in 2007). In parallel to his research activities, the applicant imparted two under-graduate courses from the Materials Engineering degree at UPM in 2008 (60 hours). In July 2009, he defended his PhD thesis entitled, “Crecimiento de nitruros del grupo III por epitaxia de haces moleculares para la fabricación de diodos electroluminiscentes en el rango visible-ultravioleta”, which received the European Academic Distinction and was evaluated as “sobresaliente Cum Laude” by an international jury. After the PhD defense, he remained at ISOM working as Postdoc in a European project until April 2010. Then, he joined Paul-Drude-Institut für Festkörperelektronik (PDI) (Berlin, Germany) with a 3-year postdoctoral contract to develop hybrid ferromagnetic/semiconductor heterostructures for spintronics as well as group-III nitride nanowires for the fabrication of nanostructured light-emitting diodes on silicon and non-conventional substrates, such as metals and 2D materials. After this postdoctoral contract, he obtained a permanent position as senior scientist at PDI in 2013 becoming in charge of the institute research activities related to the synthesis of group-III nitride nanowires. As permanent senior scientist at PDI, he: (i) co-supervised 1 master thesis and 1 PhD thesis, (ii) organized and supervised the activities of Postdocs (2), technicians (4) and numerous visiting scientists, (iii) coordinated national and international collaborations, (iv) coordinated 2 R&D projects, and (v) obtained his own funds as principal investigator of a R&D project focused on the analysis of hybrid inorganic/organic semiconductor interfaces (funded with 435.000,00 € by BMBF). After 8 years at PDI, in April 2018, he moved to UAM with a Ramón y Cajal contract. There, his research interest was shifted to the development of advanced materials, in the form of thin films and nanowires, for third-generation photovoltaic solar cells and quantum information technologies. In 2022, he transferred his Ramón y Cajal contract to ISOM and the Materials Science Department from UPM, where he continues developing III-V materials for photovoltaics and quantum technologies. During the Ramón y Cajal contract, he: (i) supervised 2 bachelor thesis, 5 master thesis and 1 research assistant, (ii) imparted 340 hours of teaching distributed between master and under-graduate university courses at UAM and UPM, (iii) became principal investigator of a project funded by Ministerio de Ciencia e Innovación with 166.980,00 € to develop III-V compounds for third generation solar cells,  (iv) obtained twice a two-year contract funded by Comunidad de Madrid to hire a research assistant (45.000,00 €/contract), (v) participated as secondary proposer in the COST action “European Network for Innovative and Advanced Epitaxy”, becoming member of its management committee, and leader of the short-term scientific missions program, (vi) obtained an ERC-Consolidator Grant (2022 Call) funded with 2.808.686,00 € to develop III-V tandem solar cells on Si, and (vii) received from ANECA the accreditations as Profesor Contratado Doctor and Profesor de Universidad Privada as well as the recognition of a first six-year period of research.

Along his entire scientific career, he has been reviewer for several international journals and R&D programs, member of the organizing committee of an international conference, taken part in 20 R&D projects (including 4 EU projects), obtained 2 patents granted by the European Patent Office, and co-authored >90 research articles, >100 conference contributions (including the presentation of 9 invited talks at international conferences), and 1 book chapter. His work has received >3300 (>2300) citations, resulting in an h-index of 32 (28) according to Google Scholar (WOS).B.1. Breve descripción del Trabajo de Fin de Grado (TFG) y puntuación obtenida B.2.
