Benoît Marie Joseph Deveaud
Benoît Deveaud est maintenant Directeur Adjoint à l'Enseignement et la Recherche, Ecole Polytechnique Palaiseau.
Benoît Deveaud est né en France en 1952. Il est admis en 1971 à l'Ecole Polytechnique de Paris et s'y spécialise en physique. En 1974, il entre au Centre National d'Etudes des Télécommunications. Il mène à la fois les études sur les centres profonds dans les semi-conducteurs III-V, et poursuit ses études de physique en préparant un diplôme d'études approfondies en physique des solides. En 1984, il soutient sa thèse de doctorat à l'Université de Grenoble.
Entre-temps, son équipe s'intéresse aux microstructures et lance une recherche sur les propriétés structurales et optiques des super réseaux à base d'arséniure de gallium. Ces études mettent en évidence par exemple le transport vertical dans les superréseaux ou la quantification des énergies de transition dans un puits quantique. En 1986 il rejoint l'équipe de Daniel Chemla aux Bell Laboratories (Holmdel USA) et participe à la mise au point de la première expérience de luminescence ayant une résolution temporelle meilleure qu'une picoseconde. Il étudie les processus de relaxation ultra-rapide dans les puits quantiques.
Rentré en France, au CNET, en 1988, il dirige un laboratoire d'études ultra-rapides, portant sur les propriétés optiques et électroniques des matériaux semi-conducteurs.
Nommé professeur en physique à l'EPFL en octobre 1993, son équipe de recherche étudie la physique des processus ultrarapides dans les micro- et nanostructures et les composants qui les utilisent.
Il a dirigé l'Institut de Micro et Optoélectronique depuis 1998 puis l'Institut de Photonique et électronique quantique de 2003 à 2007. Son équipe participe activement au Pôle national de Recherche "Quantum Photonics" dont il a été le Directeur Adjoint de 2001 à 2005 puis le Directeur de 2005 à 2013.
Il a été Doyen pour la recherche à l'EPFL de 2008 à 2014.
De 2014 à 2017, il a dirigé l'Institut de Physique.
Il a été editeur divisionnaire de Physical Review Letters de 2001 à 2007.
Jean-Philippe Ansermet
Jean-Philippe Ansermet was born March 1, 1957 in Lausanne (legal origin Vaumarcus, NE). He obtained a diploma as physics engineer of EPFL in 1980. He went on to get a PhD from the University of Illinois at Urbana-Champaign where, from 1985 to 1987, he persued as post-doc with Prof. Slichter his research on catalysis by solid state NMR studies of molecules bound to the surface of catalysts. From 1987 to 1992 he worked at the materials research center of Ciba-Geigy, on polymers for microelectronics, composites, dielectrics and organic charge transfer complexes. In March 1992, as professor of experimental physics, he developed a laboratory on the theme of nanostructured materials and turned full professor in 1995. Since 1992, he teaches classical mechanics, first to future engineering students, since 2004 to physics majors. Since 2000, he teaches thermodynamics also, to the same group of students. He offers a graduate course in spintronics, and another on spin dynamics. His research activities concern the fabrication and properties of magnetic nanostructures produced by electrodeposition. His involvement since the early days of spintronics have allowed him to gain recognition for his work on giant magnetoresistance (CPP-GMR), magnetic relaxation of single nanostructures, and was among the leading groups demonstrating magnetization reversal by spin-polarized currents. Furthermore, his group uses nuclear magnetic resonance , on the one hand as means of investigation of surfaces and electrodes, on the other hand, as a local probe of the electronic properties of complex ferromagnetic oxides.
Christophe Ballif
Christophe Ballif is director of the Phototovoltaics and Thin Film Electronics Laboratoryb) (PV-Lab at the institute of microengineering (IMT) in Neuchâtel (part of the EPFL since 2009). The lab focus is on the science and technology of high efficiency heterojunction crystalline cells,so-called passivating contacts for solar cells, multi-junction solar cells include novel generation Perovskite on innovative optical high speed detector and on various macroelectronics application. It also deals with energy management with a focus on integration of solar electricity into the energy system. The PV-Lab has strongly contributed to technology transfer and industrialization of novel devices and full technology with numerous companies. Christophe Ballif graduated as a physicist from the EPFL in 1994, where he also obtained in 1998 his Phd degree working on novel PV materials. He accomplished his postdoctoral research at NREL (Golden, US) on compound semiconductor solar cells (CIGS and CdTe). He worked then at the Fraunhofer ISE (Ge) on crystalline silicon photovoltaics (monocrystalline and multi-crystalline) until 2003 and then at the EMPA in Thun (CH) before becoming full professor at the University of Neuchâtel IMT in 2004, taking over the chair of Prof. A. Shah. Since 2013, C.Ballif is also the director of the new CSEM PV-Center, also located in Neuchâtel. The CSEM PV-Center is focussing more on industrialisation and technology transfer in the field of solar energy, including solar electricity management and storage. At the core of the CSEM PV-center activities lies several "pilot lines" for various kinds of solar cells manufacturing, with a focus coating technologies, wet chemistry processes for crystalline silicon, metalisation techniques for solar cells, and a platform for developing "ideal packaging solutions and polymers" for PV modules. In addition, joined facitilites between CSEM and EPFL of over 800 m2 are available for modules manufacturing, measuring and accelerated aging. CSEM PV-center has also full team dedicated to storage and energy systems and operates a joined center with BFH in Biel for research on electrochemical storage. He (co-) authored over 500 journal and technical papers, as well as several patents. He is an elected member of the SATW, member of the scientific council of the Swiss AEE, and member of the board of the EPFL Energy center. In 2016, he recieved the Becquerel prize for his contributions to the field of high efficiency photovoltaics.
